sometimes when i start my car and drive away my rpm starts like almost popping and it makes it so my car almost dies but i have to rev the engine and it goes away any ideaS? i already tried the fuel injector cleaner

 

Don't just start the car and drive away - let the oil start to heat........and let the o2 sensor heat a little bit - THUS, Letting the car "WARM UP"........you know.........

If you just start it up and go, your oil pressure will not be as high because itl'l be thick-like. Just let it run for a bit, and then drive away. And report back to us.

 

if it doesn't work - try adjusting the idle screw to make it idle around 900 or so.....

 

yea i always let my car warm up first it does it a lot wen im parked no a hill for some reason ,, possibly my fuel pump u think?

 

Nah - if the fuel pulmp wasn't working properly, I don't htink the car would start/run at all.

 

vacuum leak?

 

whats a vacuum leak and how would i find out?

 

Sounds to me like fuel pump, fuel filter, fuel something.

Let your car idle to warmup temp, about 5-10 minutes, the fan will kick on. Watch the idle rpm's and let me know if they "jump around" or surge up and down.

If idle rpm is smooth, then it won't be a problem with air-intake, it'll be likely with fuel-intake.
