Mr Phil

Heres a video from last week of me at the strip, someone told me my timing might be off? Idk though, I've also been told that it might be because I have no rear o2s and no sims either... obviously it's hard to tell just by listening to a video recorded from a cell phone lol, but if you have any input or if you think it sounds healthy (lol I wish) just Gimme your 2 cents

Just to clear it up, I said it might be timing.. I'm no genius with cars or anything. Just an educated guess... However Phil, I have NO 02 sensors.. No upstream or downstream.. ZERO. NO MAF either. Haven't had it tuned since I changed my exhaust or did any other bolt ons. I have never had that problem with misfiring that bad.

Mr Phil

I know I saidi was told it MIGHT be off lol, I didn't say you said it was 100% off lol

didn't you replace your fuel pump or pump assembly?
i remember that you had this issue might be some1 else.
sometimes its not the Pump that's bad its the regulator in the assembly.
change the assembly or simply go with racetronix.
tune.. and you should be fine

^^ above unless you've already changed the "ASSEMBLY".

Mr Phil

Well wheni replaced the pump the car was fine, but I guessi could look into the regulator.... how hard is that too replace?

I know I said might. I just didn't want somebody coming on here making you sound stupid. I would take the critisizim basically lol.

AmDWs6

you can't change the regulator alone you must change the whole pump assembly.

any tuner or mechanic can find out if its the regulator.

oh & if you didn't tune the car after replacing the pump i think you should + did you change the filter? might as well.

Mr Phil

Filter was replaced when I got the car

I would go and check your plugs and wires. Look for damage around the boot tips (metal part) and cracks in your plugs. Tune out your o2 sensors if you don't have any o2's. Could even go as far as checking your injectors as well.

Mr Phil

Plugs were just replaced when I did the headers remember, so I hope they're not the culprit, although that would be the cheapest fix... How hard is it to remove/check injectors? I know u can let the tips soak in vinegar over night to clean them but removing them seems to be the difficult part

I haven't removed them before but if it were me... I'd go out there and tinker around. It appears to be pretty straight forward. If you do decide to mess with it, be sure to release the fuel pressure through the schrader valve on the drivers side fuel rail.

Mr Phil

Ehh I just bought some z Max and a bottle of concentrate techron
