Engine Stumbles At Idle

[88whitemanche]

What's up guys

For the past month I've been having a stumble at idle like if its going to bog out...I've done a full tune up, changed all vacuum lines, changed my idle speed controller, cleaned throttle body...and yet still feel stumbling....

 

Do you guys think it can be the maf sensor?

[Geonovast]

Have you run any injector cleaner through it? 

 

Checked the air filter?

[88whitemanche]

Injector cleaner to where? The maf sensor?

 

Air filter was changed with the tune-up. Also fuel filter.

[Geonovast]

Injector cleaner in the gas tank to clean out the injectors.  You seem to have already knocked out most of my guesses.

 

Does it run fine otherwise? 

[88whitemanche]

Yes it runs great. gas mileage seems better after the tune up and vacuum hose changes just that stumble at idle concerns me.

Click on the link in my signature and do the ground refreshing, C101 refreshing, Connector and relay refreshing, and sensor ground testing before proceeding down any other rabbit trails.

Definently wouldnt hurt to pull the plugs again and recheck the gaps......may have possibly smashed 1 on installation, chase a similar issue for months
