I just bought my 94 Camaro 3.4 V6 about 3 weeks ago and I'm having really severe gas mileage problems. I'm getting approx 160 miles to a TANK. I just got rid of my 94 3.4 V6 Firebird and got about double that, without any tuneups.
The only thing that isn't stock from what I can tell is that there is a dual exhaust put on the car. Any noticeable problems that I can tell is that for some reason, in Overdrive (the car has both OD and D), when I dont give it much gas and lightly press the accelerator, I get a pretty bad vibration. It seems to go away if I give it more gas. It also seems to vibrate alot at idle at a stop light. I really dont see much of the vibration if I'm in just Drive, but in Drive, when I let off the accelerator at highway speeds and let it idle down abit, I sometimes will get a "pop" or small backfire...basically Im thinking its an exhaust problem but could that cause THAT much of a decline in MPG??? I can take pics of the exhaust and possibly even a movie of the vibration or anything if need be...I really dont want to have to get rid of this car but I cant afford to keep it if Im going to have to put $55 in every 150miles! thanx for any help!
