Alright yesterday I put on the RB header and presilencer on my 91 rex....and the air pump and all the goodies are still on. The problem is that when I start my car that it will rev up to about 2k then just die>...? I have no clue as to why it even does this, I was thinking maybe there is a vaccum leak some place?....I am not sure...leave me some feed back thanks.

 

hmm...what else did you change on it?



replacing the ehxuast wouldnt create a vac leak ... its on the exhaust path

 

did you make sure the pressure sensor was connected after you were done? Its goes to the manifold right there and was probably knocked off if you didnt remove it to begin with.

 

yeah theres a couple of hoses that are easy to knock off ant hard to see on the big intake tube

 

as far as I know I connected it back up..I went and looked and it was connected...the only thing is....I hope that I connected it to the right line.....

 

Well I went and looked and there were two small hoses not connected.......I hooked them up and started it......it idled for close to a min at around 2k and then it died........so I suppose I am making progress......and other help?
