Thread: Top Swap having horrible idle, no power on throttle

Yeah you really need a way to scan, and you have to fix one thing at a time. It's hard to diagnose one thing when other things aren't right. Start with fixing things you know are messed up, and go from there. So your xover isn't bolted to the rear manifold at all? It's just sitting there? I wouldn't trust an AZ maf sensor either, that sucks it cost $180.

If it'll get you to work with the maf unplugged, do it. You gotta get to work, and that alone won't hurt anything if you just take it easy.

What code do you have that's setting your SES light?

Nope it's not bolted to the rear manifold at all. The front manifold it bolted to the crossover but both bolts in the back to the rear manifold broke off.
