Cold Start problem

bigal0043 · 10-11-2005, 01:54 PM

Alright i have a question. In the morning or when the car hasnt run in like 5 or 6 hours plus when i try to start it.. it has a really hard time starting it turns over and seems to catch but the rpm stays at like 400 then just dies.... start it again and it will do the same thing then do it again and it will start... Any ideas???? right after i do that i can hear the waterfall behind that dash but only for a couple seconds then goes away...

sometimes when i am going and say i was going and was in gear and switch into neutral it will stall out... any ideas???

What year and model is the one you have? Miles and any aftermarket parts that might affect it too would be helpful.

no blow off valve ?

the stall sounds like a blow off valve

the cold start could be a bad/clogged cold start injector
a cold start temp sensor/switch
or your egr vsv and fuel vsv .. i'd check the resistance of the egr vsv valve (under the intake manifold )

yea there is a bov... it is the stock one... i thought that as well but it isnt that.... i usually stall out if i am step on the gas real quick then switch to neutral... like say i back up real fast then switch to n...

how do i check the cold start injector? where is that located at?
