Lately my car has been down on power. I don't know why. if I actually tried to do a burnout, it sputters and hesitates and cant spin the tires. I was thinking fuel pump?


It doesn't even have enough to spin the tires in that video.

in this one I punched it from a dead stop and it hesitated for a minute and then goes. the only way to notice it is wide open throttle, cause it runs OK normally driving.


Any ideas? I was thinking fuel pump. the only code is a p0300 random misfire, but that's because of the cam, and its been like that since Ive had the cam in.

Fuel pump man

Sail Hatan

It would still be running ok with the weak pump? I thought they just go out. I think I'll get one just to play it safe

When's the last time the fuel filter was changed?

Sail Hatan

Before I owned it. Maybe I'll do them both.

Don't replace any parts until they are verified to be bad, what do your o2 counts look like, are they lazy? Has the car ever had a tune up etc. Check over the whole car before assuming what the problem is and throwing parts at it.

Ok I couldn't find anything wrong, but I came across a whole new fuel pump assembly. Installed it, didn't seem to help, but I'm gunna throw a fuel filter in it as well, it's only 10 bucks. Then clean the maf, and if that doesn't fix it, it's going to the tuners. Now it's just a little hesitant on take off, or going wot
