2006 Silverado performance question.

[HoodIN]

I've got a 06' Z71 w/5.3 and 102,000 miles. It has K&N FIPIK, cat back, and virtually stock other than that.

My question is about performance. It seems to run inconsistant from day to day but no codes. Some days it will flat out go and others it seems doggy. I've replaces o2 sensors, fuel rail and injectors, and coils (all needed per a GM tech), and it also has a Nelson custom tune (but it was doing this before that) and still does.

Anyone had experience with a similar problem that was solved or any ideas? Thanks in advance, John

My truck seems to do that to, but I blame it on the weather.

[HoodIN]

I've always thought the same. I guess it's to be expected although it is annoying. Just curious if mine was the only one to do it. Thanks

have you cleaned your maf sensor?

have you cleaned your maf sensor?

No I haven't. What is the best way to do that? My last truck was a 79' so alot of this sensor stuff is new to me. Thanks

maf cleaner, and a gentle touch with a qtip

Q-tip? I have only used the MAF spray.
