I was under the impression that import automobiles had a cold start feature that would boost your RPMs to around 2000 upon start up and gradually move down to standard idle once the car is warmed up, i have a JDM b16a in my car and am curious as to why my car dosn't do this.... a friend of mine has the same engine in his car and said he dosn't have that feature either... Is this a problem or normal??
TIA

one more thing, does anybody know of a website that has pictures of fully assembled intake manifolds so that i can match the vaccume line im missing up..

 

anyone

 

I was under the impression that ALL cars have this feature in some way or other. Every car I've ever owned had it, but they were all a bit different. 2000rpm isn't always the magic number, either. Depends on the temperature.

'72 Datsun 510 - fast idle cam on the carburator
'74 BMW 2002tii - fast idle mechanism on the injection pump
'82 VW Rabbit - electrically heated auxiliary air valve on intake manifold
'86 Jetta - ECU controlled auxiliary air valve on intake manifold
'89 Saab 900 - ECU controlled AIC valve across throttle body
'95 GS-R & '98 Accord - air bypass valves on manifold
'01 Saab - ECU tells the drive-by-wire throttle to open just a bit

 

in my carbed '84 prelude you had to pump the gas pedal once before startup.
Sorry though, I know that doesn't really help.

 

When you start it up cold what does it rev to?

 

Most cars idle high until they warm up. If you're referring to the 'Fast Idle Solenoid', some vehicles don't have it. 90-91 Civic/CRX Si's had them for sure, but only kick in when temperature is below freezing.

 

thats the problem, when i start it up cold it dosn't rev to anything but a boggy 800-1k/rpm... i think my injectors are getting bad too i tried starting it today and it would just crank over and over but eventually squeezed out a luggy bogged down start...
