Anyway, I plugged in the new pcm and took the car on a test drive. A few minutes into the ride, the CEL came back on. When I got home I toggled the key and codes 1684 and 0443 came up. I can understand the the first since I had the battery disconnected to replace the pcm. But what about the solenoid one? Do you think that the solenoid is bad? If so, why didn't the old pcm have the code? Could the new pcm be faulty.
What would you advise for my next step?
PS--I still have my old pcm.
A big thank you to all who can help!
Going to send back the pcm for another.
Where are you buying the remanufactured PCM from?
Did you give the PCM supplier the pcm part #, miles, VIN# so they could program that in the reman PCM that you received?
Try this before sending anything back, You probably took out the battery or disconnected the battery ground while changing the timing components.
The engine and sensor grounds are on the left fender,, with a battery ground going directly to to the stud that has several smaller ground wires going to it.
It just might be possible your grounds are oxidized like mine and caused problems, cut off and strip the wires, twist them together and use acid free electrical flux then solder them in to one hard mass. Clean or replace the eyelet and tin the eyelet and then solder the wires to it. It fixed mine, lets hope it fixes yours. I thought it well worth the time for future problems that may show their color too. Don't burn your fingers as that mass of wires, solder and eyelet get a bit hot and hold the heat for a bit.
If DC electric works like AC a bad connection will cause power problems, as voltage drops amps go up and may cause heat and damage other components, unless that just applies with electric motors. I've read where the PCM can compensate for voltage drop but there is a limit.
Are your battery cable connections shiny clean with out corosion swelling the insulation?
The code P0443 indicates that the electrical readings, i.e voltage drops etc, of the purge valve are out of the designed specification window. In addition, the purge function of the EVAP system isn't triggering the specified amount of vacuum when the EVAP monitor performs its leak test. This vacuum is measured and monitored by the Fuel Tank Pressure Sensor. The vacuum can be too high and for too long (stuck open purge valve) or it can be too little or non-existent ( stuck closed purge valve, a leak in the system or a defective fuel tank pressure sensor).

Thanks for all the info! Ptcruisersteve, I got it off ebay from autocomputerexchange. Others had suggested them on other threads. The pcm was $160 and they programed it with my vin, mileage, etc. We'll see how things go with this exchange.
I'll look at the grounds tomorrow JoeX. Thanks for that info! The terminals are in good shape and clean with no buildup on them. Just to double check. Grounds are on driver's...I can trace the batter negative cable and find it easily? The battery ground hooks to a stud with other smaller ground wires going to the same stud.

Ptcruisersteve...if you need a replacement, you might try the company I did. Even though I got a defective one (which is something that I think happens often with most reman companies like this), the company is trying to make it right. I emailed them on Saturday night, and the fellow emailed me back on Sunday morning asking for my number. I gave it to him and he called me within 15 minutes to tell me they are shipping me another right away on Monday. Now I am just keeping my fingers crossed that it works as I have an emissions ripoff, I mean test, coming up at the end of the month.
My replacement PCM arrived last night and seems to be doing the trick. No CEL so far. Guess the first one was just a dud.

Read on to learn more or schedule a visit with one of our doctors to talk about it!
When your feet hurt, you hurt all over. In many cases, ailments of the foot and ankle can be treated conservatively. This means by methods which do not require surgery. Commonly seen conditions which typically resolve with non-invasive treatment can include tendinitis, plantar fasciitis, capsulitis, neuromas and warts. Unfortunately there are instances where surgery is recommended and even some instances where it is required.
This is a condition in which there is pain and inflammation to the ligament surrounding a joint. This is commonly seen in the big toe joint, but can affect any joint in the foot. Some individuals experience this condition in the ankle as well. What is important to realize is that capsulitis is a very generic term. An individual can experience capsulitis as the result of a variety of causes. It can simply be due to an instance of overuse of a particular area of the foot, but it can also be due to a deformity in the foot – think bunions and hammertoes. Capsulitis is often treated by use of some form or protection or support which puts the affected area in a position that it can rest in, which allows your body to recover and heal. To speed the process, anti-inflammatories and icing are often recommended. If the condition improves with these simple first methods, the goals of treatment are re-directed to prevention of the recurrence of pain. When this condition does not improve, advanced imaging offers further diagnostic information which can at times reveal a need for advanced immobilization or more aggressive treatments. Capsulitis can be the initial diagnosis from your doctor, but it can be associated with a tear of a ligament depending upon the chronicity (or length of time the condition has been present) and tears require longer periods of immobilization.
Tendinitis is when there is pain and inflammation of a tendon. This can occur to any tendon and at times tendinitis can be a secondary diagnosis when another condition leads to compensation and overuse of tendons. Similarly to capsulitis, initial methods of treatment are aimed to reduce strain of the tendon to allow your body the opportunity to heal. Anti-inflammatories and icing again help to improve this condition faster. Just as with the ligaments around joints, if inflammation and overuse of a tendon is chronic it can lead to tears within the tendon. This is due to deposition of collagen within the tendon that may not have the opportunity to remodel into a functional and resilient tissue while activity continues.
Plantar fasciitis is an incredibly common condition where there is inflammation of the ligament on the bottom of the foot called the plantar fascia. You may now be appreciating a pattern with these conditions. The suffix ‘-itis’ is used to describe inflammation. The plantar fascia in the foot is a large ligament which runs from the heel all the way to the ball of the foot. Pain from plantar fasciitis can be in the arch of the foot itself, but most often occurs on the inner aspect of the heel where this ligament tends to experience most of its strain. The plantar fascia can become overstretched and inflamed with increased time on feet, a change or reduction in the support of shoes that is within the foot or even compensation due to another condition in the foot. Plantar fasciitis treatment protocols consist of support for the arch to decrease daily strain and wear-and-tear in the form of an arch strapping. Anti-inflammatories are also useful to decrease healing time and exercises and devices to stretch the achilles tendon, calf muscle and plantar fascia are necessary to reduce tightness which is commonly associated with this condition. The plantar fascia can also become torn – sometimes by trauma but most often by chronic overuse.
Neuromas are localized areas of swelling and/or scar tissue that develops at particular areas along a sensory nerve in the foot. The suffix ‘-oma’ means tumor and this is a generic term for any mass of tissue, not necessarily dangerous or cancerous. Neuromas tend to develop from pressure and friction along a nerve in the foot which causes inflammation and scarring to develop. These are most commonly seen between the third and fourth toes in the foot. People often describe the symptoms of a neuroma as walking on a pebble and will also notice tingling, burning or numbness into one or two nerves. Neuromas develop most often in a foot structure whereby the bones in the fore
