wont idle when cold

[bigal]

my buick will not idle when cold but runs excellent when warmed up i have 55lb injectors with a red 93 chip. the tps and iac are in correct settings , using scanmaster. the car wont idle, just replace maf and it seems to be a good one.

could be the O2 sensor. my car used to do the same thing w/bad injectors and now its gone away. it woulod rev up then slowly fall to a slow death.

Start with the simple things first,check for vacuum leaks from the vacuum block on top of the throttle body and from the fuel vapor canister.
