Hi I am new to this site and i've found it very interesting but i have a problem with my car.
It's Camaro 89' RS with 2.8 L V6 MPFI injection.
I have 3 main problems that I'd like to solve they are:
1. Excessive fuel consumption
2. Very Rough idle or idles very erratically(Sometimes cuts out)
3. Engine has no power

Anybody has an idea what could be a problem??

Thanks!

 

Welcome to ThirdGen.org!

There are many possibilities.

Is all required maintenance current? Filters, ignition system, fluids?

 

Everything seems to be ok I think it could be something else

 

ANY TROUBLE CODES

 

Yes There are trouble codes one is number 33 other one is 44 and I also have "Check Engine" light on all the time.

 

ok....now do a search and see what the trouble codes mean and go from there

 

The first things I check on 2.8s are 02 sensors and MAF modules... when an 02 sensor goes out, it will do everything you just described.

 

The only code I am getting now is 34 i assume it has to do with MAF sensor

 

Your assumption is correct. However, the presence of the code doesn't necessarily mean the MAF is faulty. There are many reasons a "34" can be generated with a GOOD MAF.

 

I had a 350 that did that just because the plugs were bad. I would check that first.

My second choice would be a coil with a crack in it. Open the hood in the dark and see if you see any blue sparks around the coil with the engine running. Happened to my sons 2.8 and a new coil made it run like new.

Third choice is 02 sensor. My cavalier was doing exactly all three things you said and it was the 02 sensor.

I have changed about 3 MAF sensors because that was what the code indicated and each time it was something else. I have actually never seen a bad MAF sensor.

i'd back up to Mr Vader's first reply. do the tune up maintance stuff so you know you have a solid foundation to start with then scan for codes and look a little deeper into any remaining problems.
