In the am my car cranks take about 5 to 8 seconds to start . When it starts it runs perfect . Until it is warm at normal temperature car keep hold it's idle . I had a wideband in would read in the 10s when idle fell and if I drive the car it will stall . When I start it back up take about 20 seconds of cranking and a cloud of smoke comes out the exhaust . . I have s300 my u2 is disabled . I have brand new plugs wires, and just tried the distributor and fuel pump out of my buddys car still nothing ..

 

Also forgot to mention if I pull a hose of my intake manifold my car runs perfect when warm has a high idle when cold . But at normal temperature car holds idle perfect .. Even after driving

 

Anyone??

 

What kind of mods you have?

Any chance your IAC is needing to be cleaned?

 

Changed the iac and tb still nothing. Car only does this when it's warm

 

have you tried cleaning the FITV as well?
