can anyone help.my 95 import sti will not rev above 4000rpm.when you get to 4000 revs its like a rev limiter coming in.will drive fine up to these revs and the turbo will come in but then hit 4000revs and it starts to fart.also the check engine light has come on at the same time.if anyone has a clue let me no as your help would be apreciated.

 

hi fella sounds like a boost pressure problem any split or leaking pipes or strange air rushing noises . i had the same prob mine was a split pipe under my intercooler pain in the butt too find good luck

 

Limp home mode check here for reading error codes and resting the ecu

cheers guys will have a look 2moro as intercooler was off a couple of days b4 so it may have split or moved the hose.

 

If you do find the problem you will have to reset the ecu good luck

 

cheers mate.can c this being a bit of a pain in the ****.

 

is speedo working? also triggers 4500rpm rev limit

 

speedo is not working.could this be the problem?

 

yep if speedo not working then this is one of the problems

 

will this be the cause of the problem and do i have to reset ecu as the check engine light is on?

 

yes sounds that way you can also check the error codes and reset the ecu
check here as the CEL is on there should be a code recorded.. probably get code 33.

fix the speedo and probably should be sorted.
