So im in 3rd at 6000RPM and shift to 4th. But it doesnt go in 4th. It goes in 2nd. 11,000RPM sounds sick but not good for a stock GSR motor.

SO i pull in a parking lot, and its idling real rough. Like its running on 3 cylinders. So I do a spark test, all 4 cylinders are recieving spark. I check the plugs, all of em look fine . Running short on time, I make my way home. Driving is fine, it doesnt hesitate or run rough like it would if an ignition component was fucked up.

Any ideas?

btw car is a boosted stock gsr, tuned with neptune 550 injectors

so whats it doing now?

Do a compression test.

If this is the first time you've done it, I wouldn't be TOO worried about it, at least I wouldn't think so. You may have just starved it for oil that one time and once it sits and cools down and you run it again it may be alright, just be careful with it that's all. Anyone else have an opinion?

comp. test is #1 on my to do list tommorow

i drove home for 5 miles and while driving at part throttle it drives normal. but once its in neutral and idling it idles rough, misfiring i beleive.

could i have jumped some timing?

rev limiter is there for a reason....

rev limiter does stop a mechanical over rev

Most likely a couple bent valves.If you have adjustable cam gears see if they have moved.And yes it is possible that it jumped a tooth also.

sounds like you bent some valves

do a compression test...

Bizarre

Agreed

vg7z

im praying its not bent valves

valves are easy to change if the valve guides arnt damaged

all i got to so lang is AHHHHHHHHHHHHHHHHH ****........do the easiest test first vacuum gauge...if you have a boost gauge that can read vacuum do that its easier....or check timing

lol i thought i put does'nt sorry

A compression test would be good, but a leakdown would be better....do that if you can. Sounds to me also like you floated some valves and smacked them.

qfast817

try a leakdown on it most liky valves

i agree a vac guage would be an indicator of valves being fucked... Id be willing to bet compression test is gonna make ya sad,, shitty, i did the same thing with my boosted f series. got lucky, but nowhere near 11k, 9 i think...lol but it idled fine and comp was still good</TD></TR></TABLE>

Pull off your cylinder head before buying anything, like new valves you possibly might need a new head after you see the damage.
