Check engine and wrench light on day after power washed engine
Hi guys, i was driving my truck this morning and after a clunk noise it stalled and lost power, wrench light went on and limp mode got activated. Pulled codes and got these:P102, P135, P155 and P0443. I removed the MAF sensor and throttle body, cleaned them with special spray and didn't solve my issue. My mechanic decided to power wash the engine last night so it's gotta be related. Any ideas? What else should I check/clean? Thanks!

No, he didn't ask but he didn't charge me for the job done, I mentioned i was gonna put up for sale my truck as soon as he was done working on it and tried to be nice... He's my friend that's why im trying to figure this out myself

I'd let it dry out more.
The MAF, get MAF cleaner and clean it.
Get electrical parts cleaner and open up the plugs for the o2 sensors and spray them down, same with maf.
It should be fine, prob just some water in there somewhere. Check these harnesses as well for breaks.

I did the MAF with the cleaner and i got a electrical parts cleaner. You mean the O2 sensors on the catalytic converters? Should I remove the Coil packs or just leave them alone?

Well, I just removed all coil pack, used an air compressor to blow everything really good, cleaned all connectors and cleaned MAF sensor again, checked connectors for O2 pre cat sensor (which I recently replaced) and they look good. Reconnected battery, turn truck on and BAM! Wrench light again and barely runs... I hate this truck man

I would bet there is a connector where all those different circuits pass through. It will be on one of the larger wiring bundles. Disconnect any connectors that would be in the water jet path and gently dry them with a hair dryer. It would be crazy coincidence to be an actual problem. You're on the right path.
