Computer/PCM by jdbonill
Apr 16, 2008 (12:30 pm)

I am not a car guy by ANY stretch of the imagination. I have recently had a lot of trouble with my RPM's being way high in idle. Took it to the mechanic, and after a bunch of repairs, he still said that I need a new computer (PCM). He wanted to charge me about 600 for just the part. I have found the part new at a much cheaper price, and was told it was easy to repair. The problem is, I cant seem to find the computer under the hood. Any advice? I have a 2001 pontiac grand am, 2.4L

The PCM (engine computer) is under the dash above the driver's left foot. Wait 4 Me Performance http://www.wait4meperformance.com/ has PCM for about $150
If you do replace the PCM, you will need to take it somewhere to do a crank sensor relearn routine - on the 2003 3.4L engine anyway. By the way, my PCM does the same thing and the driver circuit for the idle motor seems to be the culprit - I'll know in a few days - as the PCM is getting replaced.

i have a 1996 grand am with the 2.4 in it. the car has 239000 miles on it. personally im shocked that its still on the road. well i got my tranny replaced about 1500 miles ago and it shifts kinda hard but no biggy. now my check engine light is on and flashing. i haev no idea why. i took it to autozone and they said that my air flow sensor i think is bad.. its the sensor on the throttle body...does anyone know why my light is flashing? i would advise that everyone with a GA get rid of it!!!

With 230K on your Grand Am, your advise to get rid of all GAs seems without logic. Most high dollar German cars usually don't go that far. AutoZone is pretty good on price, (don't buy a warranty) and they should be able to show you the new MAP sensor and where is goes. A pretty easy DIY job. If you don't want to put the money into it, even with flashing lights, as long as it runs, drive it. The untimate way to recycle a car is to drive it til it stops....

Changing the motor and transaxle is very labor intensive with FWD (front wheel drive) cars. I've gotten good deals from eBay motors, but still way too much work to swap-out. The cheapest place would be your local junkyard, if they would / could do it. Don't expect it to be done quickly as they normally do work in their spare time. Quality could be a big question.
I do believe it would be much better just to sell it to the junkyard and use the money for a first payment on a 3 or 4 year old used car. Buy a add-on warranty for a year is also my suggestion, especially if you don't work on cars.

It's not. I would drive it until it dies and then give it a decent burial at a salvage yard.

service engine light by miklamar

My 1997 Pontiac Grand Am has 140k miles on it, and the engine light comes on when I reach about 50-55 mph. It acts sluggish, esp. going uphill. Someone said it may be the engine coil. If so, how much would that run to fix? Any ideas or suggestions?

Take it to AutoZone to get a reading of the code(s), they can then tell you how much the parts are. Mechanics double the price for parts and add labor. Buying the part and doing it yourself is the lowest cost, but check the internet to see what is involved. Taking it to a mechanic will be the most expensive but maybe the most reliable - just don't agree to a whole lot of extra work - it's the old "gotta make a boat payment" joke...
