So my car is getting TERRRIBLE gas mileage, It's got new plugs, wires, coils, 2 new o2 sensors new fuel filter, just ran fuel injector cleaner through it. I've unplugged the MAF to see if thats the problem, but it just runs terrible. Sometimes after I shut the car off in the garage It smells really strong of gas. It's been doing this ever since I put a new a/c condenser and new compressor in it. Any ideas? fuel pressure regulator? I drive 26 miles to work a day and it takes a quarter and a half tank of gas. Easy driving too, I usually try to keep the RPM's under 3k. Any guesses? It's really starting to get on my nerves.....
