Wife was towing on the interstate, chime and check engine light, she aimed for the exit. It died on the off ramp a mile later. Trying to start it, it turns over fast, tries to start but won't quite stay lit.
We had it towed to a shop, they got codes for throttle body, replaced it, no better.
They disconnected some sensors (MAF?) and they can get it to run but badly, very rough, and now it has a loud knock. Uh-oh. It wasn't knocking before and the engine has 80k miles on it.
1.. The only code is for the throttle body. Any clues what could cause this behavior and not throw a more useful code?
2.. The knock is a big surprise and worry. I put the used engine in the truck 10k miles ago and it has been flawless until now. It just doesn't make sense to me that a big knock would come on so quickly. Yes it has the proper oil in it. Maybe it's knocking because the spark timing is way off, or it has a severe fueling problem?
Any suggestions?
