Will a bad egr solenoid cause start problems

[Primecut4ya]

Replaced cps and connector after having hard start issues, reset ecu car fired right up, let run for 10 minutes, shut it down had to give gas to start, rough idle like a misfire, while checking things out I tapped the egr solenoid and motor smoothed out immediately. Now car starts fine on the cold start but after it's warmed up have to give throttle to start and it will spit, sputter and smoke, until rpm come up and it smooths out, IAC? TPS? MAP? Oh and 420A..

I capped all my egr vacuum ports when mine was causing a stutter under accel.

Any codes? Mine was bad and had a p0403 code. Replaced it and car runs awesome. Although it didn't run that bad with the sensor issue. Your problem may lie elsewhere like a vacuum leak or something.

If the egr valve is stuck open the car will not idle.

No vacuum leaks, just gonna do egr delete and go from there. whats confusing me is why it only happens after warm up..

Short answer: not likely

If you really think it the EGR and your strapped on cash you can always take if off (two bolts) get some carb cleaner and clean it ou tand try and work it back and forth. Or just buy a new one (recommened)

Easy way to check for leaks (vac.) spray around the suspected area (while idling) and look for a reaction.
