As the title says I get stumbles in high rpm's. This only happens at WOT, if i take foot of peddle just a tad it smooths out. There is little in 2nd, but 3rd and 4th are pretty bad. Fuel problem? or ignition?

Plugs and wires were just changed 3000 miles ago.

Any clues? Thanks

 

It sounds like something ignition related, possibly the coil or opti. You could always check your Fuel Pressure by putting a guage on the schrader valve located behind the intake.

Also, what kind of mods to you have done to your car?

 

Bone stock... no money

Check pressure at idle?

Ill visually check the coil, but is there any way to check it that would prove im not getting good spark? same with opti

 

You can use a multimeter to check the coil. There should be no more than 8000-8500 ohms.

 

Did you ever solve this problem? Sounds exactly like whats happeneing to mine...and my scanmaster points towards fuel.

 

check the fuel pressure mine was doing the same thing and was the fuel pump


whats money really

 

great, how much did that cost? I know you have to drop the gas tank to do that....

 

I have had this problem for a long time.
What rpm does it occur?

 

uhh....its not really RPM..im fine down low, even when I floor it it pulls like a beast...just up top. The lowest I had it do it was at like 50 mph at WOT...and its reallly bad on the highway going from like 70-120...takes a LONG time to get that fast cause its soo bad.

 

i had the same problem and it was my coil.
