96 explorer sport rough idle and start up

[bigjack216]

Well I've replaced the egr valve cleaned out my maf and also seafoamed my truck the idle seemed to improve until this morning. Now when it starts it seems like it wants to stall and the idle is rougher than ever any ideas what it could be should I just take it to a shop any helps appreciated.

Will definitely look into that just looking for as many suggestions as I can right now truck don't even have 100k on it grandma never took care of it though and I just want it to run smooth thanks for the info though.

Check for a vaccuum leak arount the intake spray carb cleaner around it. Check the vacuum hoses 6 major ones going to the intake. Make sure that the hoses coming from the PCV valve are not cracked where they come around from behind the intake.

Going to check that to it's weird though check engine light just came back on and the error came up as an o2 sensor could that cause what I saids happening

 

[gonenuke]

what was the code?

 

[rickybobby]

A bad O2 sensor can cause all kinds of problems. We need to know the code number to help you diagnose it properly though

Don't know the exact error code haven't had a chance to go to auto zone again I know it was something about bank 1 was and a high current
