Although I find it hard to READ your post, I'll take a guess... perhaps the car is hitting some sort of a boost cut (overboosting), or perhaps there is a fuel pump/regulator problem?

Good luck

 

arent those cars mass air cars ? id look for vacum leaks 1st.

 

or ecu went bad

 

pretty broad question, but id double check and make sure your not low on vtec fluid

That would have been funny if he where talking about a Honda

But hey there is always one in the crowd

To the OP it sounds like your boy is having problems with his ECU

That was the joke

either way theres really not enough information to troubleshoot this....

 

I too thinks its MAFS related.

 

yea i was readin online it they said it seems like the fuel filter is goin almost hes boostin 8 all the time so could that b a problem

 

when my poopra was running, the mass air flow sensor (the big hunk of plastic by the air filter) went bad. it caused it to jerk and want to die whenever i gave it more than like 25% throttle. check that and your vacume connections.

 

thanks goin to try it

 

I have some experience with these cars... Does it only do this when trying to make boost? If so, theres probably an intake tube that came disconnected. I've seen the tube right off the turbo compressor outlet come off and we experienced the exact same thing. Car would run fine, then when you step on it it would bog out and rev down... That particular pipe even looked like it was on, but after removing the intake we found it had popped off...
