A real bad fuel smell probably means fuel or vapour is leaking from somewhere and it could be leaking out or leaking in and either could cause bad running.

A visual check of the fuel and vapour system from the filler neck to the engine is needed to ensure there is no leaks. If there are no external leaks it is likely the leak is internal, probably via a stuck injector or similar...

2006 ford Taurus I change spark plugs and wires and coil packs but it is missing real bad and u can smell gas it runs real rough


I had a similar sounding problem on my old 1993 Lexus. In my case it was the car's computer. The capacitors on the circuit board went bad and it caused the fuel injectors to be constantly open. This flooded the engine. It would run, but very badly and it blew a lot of white smoke out the back. I replaced the capacitors and the problem went away.

If the smell of fuel is there,check the plugs.Are they all firing.Look at the plugs and see if any look different to the others in color.If so check that cylinder.Check the lead to that plug.Is it ok.At idle,pull the lead on and off and see if the revs drop.If you get a zap,all is good:) Or use a heavy rag.Check all this first.You may have an 8 that is running on 6.Basics 1st.Hope this helps

Hi have an audi a4 which has a very rough idle and if left running starts to smell, the smell is really bad if you open the drivers door the smell appears to be coming from the middle of the car also loads...


Your car is running extremely rich and the smell you are experiencing is raw fuel in the catalyst. If you keep driving this way the cat will clog and need replacing. You probably have one or more defective ignition coils, or you coil driver stage has gone bad (mounted inside the air cleaner housing)

96 chev y truck 4.3 revs 2200 rpms when you first start it.


Have you tried any fuel system cleaner through tank, just to see if that might help. Perhaps running low on fuel, sucked up some dirt from bottom of tank.

'87 Audi 4000 Quattro - vacuum advance problems.


On the vacuum line that operates the advance on the dizzy, there is a plastic piece that controls the upshift light, it has a two terminal connector and an adjusting screw on one side. Today I bypassed this piece, my car revs willingly past th 4000 mark and continues to build power. I assume this piece or the small hose it uses was leaking. Sweet.
