OK For the last two months or so my check engine light has been coming on and off. While the light was on i took it to autozone so that they could tell me what the problem was. They hooked up their little computer gagdet and they told me it was a multiple random misfire (P0300), i think that was the code. Any ways, the light will come on about every two or three weeks and stays on for a day or two then it turns off. Ive checked the spark plugs and the wires and they are fine. I checked them with a ohm meter. I have a wheatley tune for 93 octane, catless, and a bullet muffler, rebuilt tranny with a vig 3200. what could be my problem ??????
BTW i posted in this somewhere else but got no responses !

 

did you get some bad gas?

 

i doubt its the gas because ive filled it up about 8 time since the light started to come on and off

 

did you have any lean codes to go with the 300???

 

lean codes??? the guy at autozone just told me that it was a multiple random misfire and that was the only code showing.

 

do a compression test

 

your misfire codes need to be set higher or your injectors need to be cleaned.

 

why do you say my codes need to be set higher? and how would i go about doing that ?

 

your miss fire settings may need to be set higher.

 

the only thing is if he has no cam that should not have to been done that is what causes miss fires

do you feel it miss fire
