SOURCE: 1996 Pontiac Grand Am overheating

If its the 3.1L it could be your intake manifold gasket , the material used for the gasket does not react well with GM's Dex-Cool antifreeze. The leak may not be apparent at first, but I would pressure test the cooling system. If you look at the front of the motor by the belts , try to peek down at the intake manifold and check for slight seapage to an obvious leak.

If its either of the Quad-4's they were notorious for heads warping or cracking.

sounds like security system problem...to re-set, put key in ignition, turn to run, till security light stops flashing. turn off then start car. See if this helps!

SOURCE: CODE PO102 after Mass Air Flow Sensor replaced

Most faultcodes don't disappear automaticly, the have to be 'reset' manually after repairing. It sounds like the code didn't get erased after replacing the MAF. You could try to disconnect the battery for 10 minutes (disconnect and reconnect the negative (-) pole), which should erase the code.

Whenever the engine light still comes back on after that, there probably still is some (other) problem ...

a bad mss air sensor would cause this, but your engine lights(check engine) should be showing.. Trust me; if you didn't have a crank sensor; it wouldn't run at all. A simple test for you in vaccum lines. get a bowl of soapy water; and while it's running;slowly over each line, liberally put water and soap mixture. If it's sucking air it will bubble at that sight. But a problem with 3.1, and 3.8's(Dorman makes these) are the intakes. They have a problem(all of them!) where a faulty manufacturing problem, causes the back seal to blow out and warp the manifold. You lose vaccum there, and it runs awful. It's about a $179-199.00 part(comes with everything you need in kit) at OReilly and Carquest and Advance . I'll bet that is the dog in this hunt! Good luck

SOURCE: I have a 98 sunfire GT, ABS light turns on and

Based on your observations you have bad speed sensors if the ABS if fine on straight line. The turn is bringing them out of specs and causing issue. Pontiac is a GM product and therefore has a Kelsey ABS control unit and two speed sensors that feed it. The Kelsey units are KNOWN to go out in GM and are very expensive. NHTSA looked into it but since the brakes work without it, they said no recall. So GM isnt doing anything for older cars like yours and mine. You can see about getting it fixed but dealer will charge $1200 plus. The speed sensors are expensive but less so than the unit. My suggestion is to have a dealer look at it for diagnosis.. this is usually an hour of labor at normal GM dealer rates $85-$100. That way you have a definitive. Once you have the definitive you can then decide how to progress. If it is your Kelsey unit you can get a reman one from ABSFIXER.COM for much less than dealer and if you have a trusted mechanic they can follow instructions on website to do replacement. I would have speed sensors checked first though.
Good luck

My 93 jeep grand cherokee is not getting fuel...if I disconnect the negative post for awhile and then reconnect it, the jeep gets fuel and will run....what is going on?


If the check engine light does not light up on the dash when you turn on the ignition, at those times when your jeep doesn't want to start, then your main jeep ecm is in need of repair. The fuel pump relay will get energized only after that check engine light comes on. It's a known problem, especially with the first and second year production Grand Cherokees, 93 and 94.

Engen light oonly comes on somtimes on dash not on no start


sounds like a short in your ECM. (electronic control module) the computer that runs your systems. it also runs the check engine light and lets you know when a sensor or something isnt working. you will need a good mechanic that knows how to do the electronics in a car.

My check engine light activated on my 2001 Jeep Grand Cherokee Laredo - what does it mean?


All modern cars have this generic info light. You have several options:
1) Free (sort of) most oil change places can check it.
2) Buy your own OBDII scanner, about $100 bucks, works for all '96 and newer cars. Gives peace of mind that YOU know what is wrong even if you can't fix it.
3) Take to mechanic and hope they are honest and don't take you to cleaners.

Generally this light is tied to the emissions systems. Your car won't pass a smog check but it may run just fine. If you are capable check all your fluids especially the oil. Good luck.

Check gages light turns on and doesn't go off. Already had the oil changed, the oil pressure needle keeps marking 0. It had the same problem once but I changed the oil and kept working fine; then about 2...


At this point I would strongly suggest that you have your mechanic hook a mechanical oil pressure guage to the engine and make absolutlely sure that the pressure is up to manufacturers standards. It may simply be a failing oil pressure sending unit, but, until you know, it could turn out a lot more expensive! Thank you, Dana
