Nickel and diming

Sorry long winded.
How heavy of a mis fire are you seeing? Also there are some issues with the interface of some after market O2 sensors as far as their operating parameters. I can't recall who makes them for Mopar (NGK maybe) but everything I found on line when I dealt with my Durango said use the OEM or the company that made them for Mopar. Also don't loosen and rotate the distributor, If you turn the distributor there is like a "phasing" that has to be reset thru the obd with an oem style scanner such as snap on. I lent out my 99 factory manual but there also several sensors that share a power source and I believe they were iac, crank and tps and passes thru the heat circuit for the forward 02. So any one of these being out of range can cause an issue that won't necessarily throw an obd code. There were also issues with control modules failing and doing wacky stuff. Don't own it anymore. Not trying to muddy the waters, but just putting out some info I recall that I went thru. And as mentioned here and another thread the plenum gasket, high oil usage, pinging, low power and crappy mileage.
