Hello are you still answering question I have a 2002 Hyundai xg350 I just bought car engine light turned on. Took at autozone and other garages. Codes for tps came up.

Rescan for codes and check fuel pressure with a gauge autoparts rent it. Check vacuum at idle on intake if 15" or below suspect plugged exhaust

I'm pretty sure it's a plugged exhaust is there any way to clean it without removing? Because there like two metal mesh covered conveyor looking things before the converter that looks like it's getting blacker every time I try to mess with my car like exhaust doesn't want to pass. I tried the trottle body nothing tps replaced how do I go about a plugged exhaust
