If I red line 1st and slam it into 2nd and floor it my car stumbles, then I let off the gas and floor it again and its fine untell I slam it into 3rd and it does the same thing as in 4th. please help me!!!

 

what exacty do you mean by stumbles????

 

Its like its not geting enough air or to much fuel

 

does the car vibrate, or feel like it is going to stall, or does it not accelerate like it should, likke your clutch was sticking

 

no its the engine Im running 93 oc fuel it fells like its going to stall

 

i dont know man, maybe someone else has had a similar problem I have had anything like that happen to me...sorry no help

 

thanx for trying man, I hope some one can help me

 

doess any one know whats wrong with my car

 

maybe your not making enough hp to spin the tires and the cars doesnt like it. Try solids motor mounts. Do you have SOHC or DOHC? Your engine maybe be getting old and beaten and simpily doesnt have the juice to spin the wheels!

 

I have DOHC

 

Oxygen sensor, maybe.

 

At what RPM does this stumbling occur?

 

around 4-6k but only sometimes

 

if your car stumbles, its probably not getting enough fuel,
did you ever change the fuel filter?


my car used to stumble at low rpms but that was an ignition wire problem

 

My car stumbled above 3500rpm and had no power. I changed the oxygen sensor and it was fixed. That is probably your problem.
