another cold start rough idle
car runs really rough when first started and feels like it has a miss until it gets to normal operating temp . this is what i have done so far ,
i checked plugs / wires , replaced the CTS & fuel filter .
injectors & regulator were replaced with new factory ones about 10k miles ago .
checked all the vacuum lines and sprayed starting fluid around the gaskets to see if there were any leaks .
checked voltage on TPS .
cleaned and set the IAC .
searched the forum
i am going to check the fuel pressure as soon as i get my hands on a gage .
where would you go from here ? this is really turning into a project and it seems to happen a lot with these cars according to this forum but i cant seem to find a solid answer as to why ...
