SES light or any codes?

[BLLDOGG]

no light....

If you are not sure if your fuel filter/plugs are original, well...how long have you had the car?

When you turn your key on (not engine) does the SES light come on?

ummm...im stupid, i swear. yes, the ses light works. i look at it everytime i turn the car on. no SES light is going off.

yes, not sure if anything is original or not. filter is dirty and the fuel filter could be stock...dont know but the fuel filter wouldnt make it run rich so.....it was going to be replaced unitl this problem arose

• Fuel pressure high - The system will go rich if pressure is too high. The PCM can compensate for some increase. However, if fuel pressure is too high, the system may go rich</font>
• Fuel injector(s) faulty</font>
• Check the EVAP Canister for Fuel Saturation. If the EVAP Canister is full of fuel, check canister control and hoses</font>
• Disconnect the MAF sensor and see if rich condition is corrected. If so, replace the MAF sensor.</font>
• Check for a leaking fuel pressure regulator diaphragm by checking the vacuum line to the fuel pressure regulator for the presence of fuel.</font>
• An intermittent TP sensor output will cause the system to go rich due to a false indication of the engine accelerating.</font>

thanks but alittle to technical for me [img]redface.gif[/img]

time to go studying on how to do all this :(


would a bad O2 sensor(s) cause this too?

Unburned fuel will be black smoke, not white.

SPend $30 bucks and give that poor car a tune up! It needs it from your parts desription.

Sounds like you are burning oil from somewhere.

its more gray. im thinking the smoke might be just from it being cold cause thats what it looks like. im more worried about the fuel....right now

yeah i know i need that stuff changed. trust me. im not letting this stuff fall to the side. i just dont have the money. after christmas though. my mom told me my car is going to be living in shops getting things fixed like speakers and ignition cylinder and other little things i dont want to do....

Have those injectors checked for leaking after the engine's shut off...

1 can of BG 44k would do some good.

If you said #2 & #5 I'd say coil, but doubtful you had 2 go at once. Replace the air filter and spray out the butterfly and into the intake with some TB cleaner.
