Hi Im David, the pcm is telling you there is a problem.

Cycle the key on off on off on...leaving it on.

Watch the odometer display and see if it changes to reveal a 4 digit number.

Expert:  david craig replied 4 months ago.

just checking in to see how its going

Customer: replied 4 months ago.
My friend ran the code and it showed four total. 2 of which were showing rich. So we changed the plugs with exception of number 4 the easiest to get to is the hardest to break loose. Apparently the person who put them in tighten them too much. All three so far were completely fouled Even by changing the 3 the engine started and is running. Any suggestion on how to get that number 4 plug out without bringing the thread out the head?
Expert:  david craig replied 4 months ago.

spray a bunch of wd40 into the hole. let it sit for a hour.

Customer: replied 4 months ago.
Would it be advisable to keep doing that for a day or so and drive it. I heard the aluminum head will shrink and I thought that might allow the penatrent in more Thoughts
Expert:  david craig replied 4 months ago.

no, it will expand and let more penetrant in heat expands metal

just checking in to see how its going

Customer: replied 4 months ago.
At this point because the plug appears frozen inside the head. When I try and loosen it just remains tight to turn. It does not appear to break loose. Because of the location and me wanting to take precautions I am spraying the plug with penatrent spray like PB blaster each day and driving normal. I was going to try on Monday regardless of the outcome. Any othe advice or suggestions
Expert:  david craig replied 4 months ago.

maybe use heat.

Customer: replied 4 months ago.
Can I accomplich that by trying to change while the motor is hot. ? The plugs drop in from the top of the motor into a caisson style plug chamber. Then there is a long boot that connect to the plug. There is no real way to into heat with things like a torch. So that is what I was asking would the heat of the motor help
Expert:  david craig replied 4 months ago.

absolutley. the hotter the engine the better.

Expert:  david craig replied 4 months ago.
