Chevrolet Camaro does it need a new fuel injector??

Question

have been having problems with my car. It's a 1995 Chevrolet Camaro v6, 3.4. It has almost 150,000 miles on it. Lately when I have been driving my car it seems to idle a lot, and when I go to press the gas it's like it doesn't want to go. The temperature control goes from 160 up to the next line. When I'm at a stop sign it will act like it wants to keep going and jerks some. It also I think backfires some. When I get home and turn the car off it makes a sound like the engine was heated or something. And sometimes smells like gas when I get out. We put a new filter on thinking it was that but it wasn't. I heard it was my fuel infector. The check engine light comes off and on all of the time. Also, black smoke comes out of the pipe in the back. Anyone have any tips??

Answer 1

I would check your temp. sensor. From all the information, it sounds like that's the most common problem for all of it.
If it's telling the computer the engine is cold, the engine runs full rich.
If it's reading the engine is cold, it will not turn the radiator fan on and cool the engine when needed.
So I would have it checked by a professional. So you don't end up swaping parts and spending alot of unnessary money.
hope this helps!

Answer 2

sounds to me like you have some major issues with this engine. mainly it sounds like the rings are shot by the temp increase and the black smoke that is coming out of the exhaust. have the engine compression tested, that should give you a good idea of where the problem lies. another problem coul be the timing chain and gear it only take it being out by a couple of teeth to cause very poor running. had this problem with my 90 camaro and it ended up being the timing chain and gear.

First, you need to have the codes read. This can be done at some auto parts stores for free. I wouldn't do anything before this, don't start buying parts until you have some concrete evidence of the problem. Throwing money and random parts at it won't fix anything.

For the record, I doubt it's an injector. I'd be looking toward MAP/MAF sensors.

Answer 4

It sounds like all the fuel isn't being burned, hence the smell and smoke. Since you have fuel, check for air (filter) and spark (plugs, wires, distributor).

Answer 5

I BELIEVE YOU HAVE TWO PROBLEMS ONE IS POSSIBLE FUEL INJECTOR OR IGNITION THE OTHER IS A CLOGGED CATALYTIC CONVERTER. TRY "BG44K" FOR THE FUEL IT IS THE ONLY ONE APPROVED BY PORSCHE, MERCEDES AND FERRARI AS AN ADDITIVE SO IT WON'T DAMAGE YOUR ENGINE. ITS ABOUT $20 AT NAPA. A GOOD MUFFLER SHOP CAN REMOVE IT FOR A BETTER LOOK. TELL THEM YOU WILL GET TWO MORE ESTIMATES SO THEY DON'T SCREW YOU.

Answer 6

Black smoke...Too much gas, or not enough air.
