So yesterday i replaced the canister purge valve in the evap system due to 2 different error codes pointing towards it being bad. Also did a wheel bearing replacement new wires and new spark plugs due to the fact the old plugs were burnt and gapped at like 0.065. Ever since pulling the battery cable for a few hours to reset the codes while doing all this work the car now stutters a lot and has trouble idling. It also smells like its getting too much gas. It will randomly stall whenever i let off the gas and coast or slow down for traffic lights. Looking for where to look Now. Is it just the computer needing to re learn everything and i just wait it out? Do i need to pull the throttle body and thoroughly clean it? Some other sensor i need to look at? Thank you in advance for advice.
Im Walter. New to this thread.

 

I'd check the plugs and wires first. It's possible there's a bad connection or the gap on a plug got closed while installing them.

 

Checked plugs and wires. Issue existed before new plugs and wires. Gap was correct wires all had good connections. Dealership wants $104 plus tax to diagnose each sensor and tell me where the issue is. Guess ill post here next month with the fix. Each sensor is over $100 each i don't have money to take shots in the dark

 

What were the codes you were getting?
