What would cause a pop out of my exhaust multiple times at idle? I've noticed since the weather change I've had a really lean idle by my wideband....

 

A misfire..any cels?motor tuned?

 

No cels and motors tuned. Car runs great no hiccups anywhere but here..

 

Cars tuned on ectune. Precision 1000s. Built motor, doesn't smoke..

 

Lean misfires are common at low load, low-RPM operation with an injector like that.

That's what you're hearing.

 

most likely a little lean at idle. those pte injectors like to run a bit on the rich side at idle. wont hurt anything, pretty common. the newer style injectors like the injector dynamics line up got rid of a lot of the lean idle pops.

 

Yea that s what I was thinking cause other then that car runs great. Just was curious.

 

Definitly jst a lean misfire

 

ive noticed the bigger precisions like a relatively rich idle in order to idle smoothly. Ran into this on several occasions. trying to tune their idle to 14.7-15.5, they just didnt like.

take the car back to your tuner and have him adjust the IAT fuel trims and possibly your warmup enrichment.
