Customer Question

I have done some repairs on an 01 pontiac aztek 3400. I replaced an ignition control module, one coil pack, upstream o2 sensor, air filter, spark plugs and spark plug wires. I fixed all the codes associated with a misfire and o2 sensor. Check engine light is now gone however the car will do a hiccup on fast acceleration. I count three hiccups on one accelaration. If i press the gas softly it will accelarate smooth. Idle is a little rough. Note: i did loosen plenum bolts and retightened them after cracking the seal. However when i spray carb cleaner around the gaskets and places where vacuum leaks would be there is no change in idle. I need help!

good afternoon my name is ***** ***** I will assist

the idle will not change. the pcm will change the long term trims to adjust to load. it may be seeing too much air and you have a lean back fire.

do you have a scan tool that reads long term trim percentage???
