I am very dissapointed i just bought my GTA and i was driving it earlier and the check engine light comes on so i am like g0d damnit so i drive it home and park it.A couple hours go by so i go out there to start it starts fine check engine light is gone so i am like cool so i am driving it tonight and i step on the gas and it starts pouring smoke out the exaust and smells like gas and some other funk A-s-s smell and the car starts running like absolute dog shiiite.Any suggestions as what it could be. 02 sensor maybe?I have come to relize that if i cruise around in it with out stepping on it no light. step on it, lots of smoke and the light i stepped on it both times and both times same result i also put a new air intake sytem on it yesterday A fluke? or did i damage the MAF but if it is the MAF why can i cruise around with it fine untill i stepp on it?
Thanks ahead of time.

 

check the codes. and then go from their.

 

Let's see here Where does smoke come from? (oil?) How does that happen? (it get's in the cylinders?) How does that happen?

1. cracked rings
2. cracked piston
3. bad head gasket
4. bad intake gasket
5. bad PCV valve
6. cracked cylinder wall
7. broken valve seals
8. wore out valve guides

The smoke is probably oil from the cylinders being afterburned in the Cat. Conv. You need to pull your plugs and find out if any (or all) of your plugs are black, and run a compression test. The compression test will eliminate problem 1,2,3,6. if compression is good and equal. then look for problems 4,5,7,8. CHECK your codes! They probably won't tell you what the problem is exactly, but they will help steer you in the right direction.

Did I miss anything anybody? If I had to guess, your probably getting an Oxygen sensor code from sniffing some bad air!! (not you, the sensor).

 

the 02 is prolly contaminated with oil

 

If it was oil burning in the cat wouldnt it smoke all the time and not Just when i stepped on it?Cause it dont smoke untill i floor the son bitch.

 

There's no need to be guessing before you retrieve the trouble codes. If you still need help after you have those, you'll actually get some information that you can use to solve the problem.

Rather than drive it into a river, just let me know where you parked it and where the keys are.

Let's not scare the kid to death. The smoke could also be fuel not being burned correctly. Timing may be off, gas could be too low octane (causing detonation and lots of smoke), cat could be clogged. There are a number of things it could be that don't say engine death.

On the other hand, the trouble codes are most important. I bet, if they go away as soon as the car is turned off, that they are probably saying "multiple cylinder misfire". Check your plugs and see if they are soaked with fuel (or oil). Try using 93 octane and see if it goes away. If not check your timing. I'm sure someone around here knows the proper base setting for your application.

Also you may not be getting enough fuel if it is sputtering. I've seen that make smoke too. Check your fuel filter and your fuel pressure.

Try the simplest things first before you look for a cracked block or a destroyed lower end.

 

Yeah, what he said. I had a PVC valve plug on me once. The car started running like sheet. 2 qts. of oil dissapered and all my plugs went black. I started freakin out as I had just rebuilt the engine and had less than 5k on it! After a couple of day's on a bum trip trying to figure out what I had done wrong with no luck I finally took it to a factory Mech. and it only took him about 30 min. to figure it out. I would have kissed his boots, but they were greasy!!

 

Did the pcv valve make your check engine light go on? Because mine is giong if i dont even floor it now it is getting worse it just comes on if i drive more then 20 minutes now its starting to get annoying i guess it could be a combination of pcv and 02 sensor this car sat for about 2 years out in some ones yard so i am sure the sensors are all bad.

 

If there is a leak on the fresh air side of the PCV system it can set a MAF code. Id pull the codes rather then continue to speculate.

 

No. My car has mostly sat for 20 years. To the best of my knowledge, none of the sensors are bad. You either need to wait ten times longer so your sensors are all "seasoned" as mine (and are all working), or you need to start diagnosing the problem. My ECM is not reporting anything wrong. Apparently, your's is. All you need to do is listen to it.

You are presuming that all the sensors are bad. You have no evidence of that. To the contrary, it is more likely that only one of the sensors is reporting an out of tolerance condition. That may be due to a failing sensor or not. You could replace every sensor on the vehicle, the PCV, the cat converter, and anything else you can think of, and still have the same issues.

You'll never know until you find a paper clip or jumper wire and retrieve the error codes.

Is there anyone else that wants to suggest pulling the codes from the ECM? Perhaps 8-10 suggestions just aren't enough to convince someone.

If you need instructions to understand just how easy this is, just search or ask. Taking the long way around is not going to make it any more satisfying.

 

Hey Vader, Why not send him the diagsostic terminal diagram and code list? That would be blunt!

 

see a pattern

 

mabe he dosen't know how to pull codes?....I forgot what what pins you have to jump...I haven't done it since 2001, when I swiched over to edelbrock EFI, I'm sure someone here can tell you, but all you have to so is take a wire (or paper clip) and jump 2 pins on the diognostic port, which is above and left of the center councile, and the ck engine light will flash the codes, you will alaways get a code 12(no distributor refrence...engine not running....DO NOT CHECK THE CODES WITH THE ENGINE RUNNING), which is 1 blink, a short pause and than 2 more blinks, it will do any it has stored 3 times, and than go on to the next one, if you don't know what the code means I'm sure someone on this bord has the breakdown on what each one is, just post it and we can help you from there

 

Good way to put it sqzbox, lol
