Ok here's the skinny... no use wasting time with a long story...
97 XLT
4.0 v6
Installed an intake with a MAF adaptor. Carefully removed my MAF sensor, making sure not to break small wires. Carefully transferred MAF sensor to new intake. Continued with install of intake. (Used OEM piping from throttle body to the metal tube that the MAF sits in from the factory.. didn't want to deal with all that wiring. So basically all I really *replaced* was the paper filter and the MAF tube with aftermarket. When I started the truck back up after this, it ran like CRAP... sputtering, popping... I let it run for a while and it seems to even itself out. So I move it up from my garage to the driveway, turn it off. Turn it back on, same story. That was yesterday. Today I had to drive 4 hours home in the truck, and the Check Engine light has been on consistently. At the beginning of the trip, the light would actually FLASH, and I would lose a LOT of power.. like.. barely moving forward. So I stopped by an AutoZone to get the code(s) pulled, and here's what he came up with
o2 sensor failure Bank 1/2
Misfire 3,4,5,6
MAF failure
So I'm going WTF. I was super careful with the MAF, made sure everything was reinstalled EXACTLY like it was from the factory (save for the aftermarket intake, of course).
Any ideas on what I broke? My fuel efficiency doesn't seem to be down any (I was averaging 23mpg on the highway), which is what I've always been taught to look for with failing o2 sensors...
The misfire I think is caused by a bad ground wire off my battery, which will be repaired asap... am I barking up the right tree with this?
Just wondering if anyone else has had problems like this with air intake installs.
