Hello,
This is my first time posting to a forum for a vehicle I've owned lol so bear with me if I don't include everything you may need to know. So, I have a 2006 4.0L Limited with 223k miles. Recently changed the valve cover gaskets along with the intake manifold gaskets, spark plugs, and spark plug wires. Was running fine before all this was done minus the oil leak from bad gaskets and a rough idle from really really old spark plugs. Still needs many things to include a brake fluid flush, power steering flush, radiator swap, and suspension rebuild. Assembled everything, went to drive and died several times within half a mile. Mechanic diagnosed it as exposed wires for the mass airflow sensor, fixed that, car became drivable but still rough. Couldn't go over 2.5k RPM, couldn't accelerate fast, and when in "manual mode", the car struggles heavily but does not die. Also idled SUPER rough, coming close to dying shaking the car violently and then jumping to 2k RPM for a while. Also is running super rich. Replaced the sensor due to a "low voltage mass airflow sensor" code, P0102, some things are better but others not. For example, I can go up to 4k RPM before the engine starts to buck and choke, accelerate decently, still running super rich and you can smell the exhaust fumes, but I still can't really drive in "manual mode". The idle is much much smoother, sits around 500rpm at temp. However, I am throwing several codes still - P0102, P0155, P0443, P0135, P0141, P0161, P1000, P0403. These are a lot of codes to throw suddenly after a simple valve cover gasket change, and I did not touch any of these sensors besides the mass airflow sensor. Anyone got any clues?
