my car is hard to start after it sits for awhile over night or while i am at work. 4-6 hours.
Dosen't matter if it's hot or cold outside .
run very rough have to play with the gas to get it to run this goe's on for about one minute then it runs fine. ther are no error codes and i have replaced
or tested the injectors ,tps,iac,fuelfilter,plugs ,wires,pcv,airfilter,tempsensor,iats,.
can this have anything to do with the airpump it's eletcric and runs for 65 seconds at start up could it be blowing past the egr valve? I had that apart also
it didn't look bad? sory i did check pump pressure and bleed down all ok

Hello

The EGR may be malfunctioning and I don’t’ have test procedures for that. I didn’t see where you had tested the fuel pump pressure though.

If you are not throwing any codes then I would test my fuel pressure to see what it is doing at this time. The fuel pump doesn’t have to totally quit to be bad, it can be intermittent.
