i am having a problem with my fuel system. all of the drivers side plugs are fuel fouled and the passenger sides are fine. the plugs and wires are new, opti, and o2's. i was wondering what else it could be? someone told me the computer is messed up was just wondering if anyone else has had this problem.

could be fouled injectors?

 

It sounds like your injectors are staying stuck wide open and dumping a bunch of fuel. You may want to get them checked out.

 

i have ohmed out the injector and they seem fine. i dont know of anyother way to test them. and i would be wierd for just the drivers side only to messup. wierd but not impossible i guess.

 

have someone prime up the fuel system inside your car and you can listen on the drivers side to see if u can hear a seaping sound. If so, its your injectors leaking. It happened to me on friday, just in an extreme way. When i changed the oil it had 2 quarts of gas in it from a fuel injector stuck open.

 

If ALL your plugs on one bank are fouling, and ALL the plugs on the other bank are not, its not likely a fuel injector or fuel system problem. This will happen when you have a "false lean" on the bank that is fouling the plugs. Something is telling the PCM that the "wet" bank is running lean, and the PCM is adding a ton of extra fuel. But since it isn't really running lean, its adding too much fuel.

Typical causes are an exhaust leak on that bank before the O2 sensor, misfires on that bank, or an inaccurate O2 sensor - contaminated sensor, bad ground, poor wiring.

 

so you dont think there is any way that this could be a computer related problem? i am not arguing but i have been told that. just tring to figure out what is the matter with my car. i have ohmed out the o2s and they seem to be fine. and there is not exhaust leaks.

 

If you mean "a computer problem", as in the part of the PCM that runs one bank is fine and the part of the PCM that runs the "wet plugs" bank is screwed up.... no, it isn't a computer problem. It just doesn't work that way.

If you mean one bank of the system is being screwed up by the PCM because the PCM is getting bad info from the O2 sensor... yes, it is a computer problem. That's what I tried to explain.

What does "i have ohmed out the o2s and they seem to be fine."? I'm not aware of any way to check the sensors with an ohm meter... in fact you could damage the O2 sensors with an ohm meter.

Might want to explain all the things you have tried to do to sort out the problem.

 

How is this possible?

 

An ohm meter measures resistance with a slight current. This current can damage the zirconium sensor element in the O2 sensor. You need to use a meter with an extremely high impedance to insure you do not damage the sensor. You can cause the same problem by trying to measure O2 sensor output volts with an incorrect meter.

 

i replaced the oxgen sensor on the wet plug side and it is running now. the sensor was not that old maybe a year or so. but now i am having a different problem after i drive the car around for a little bit and come to a complete stop the idle falls and few hundred rpm and then jumps back up again. it will do that about two or three times and then it will idle fine. any ideas?
