Alright, so little back story here. My truck's got a bad exhaust leak right now that I haven't been able to fix yet. I have the parts, but haven't put them in. The leak is right behind the y-pipe, the pipe broke clean off after the 2 pipes come together. It's very roughly patched and has been doing ok. I only drive 8 miles to and from work each day, and haven't been driving it anywhere else.
Tonight, I had to go to the parts store to pick up the remaining bits and pieces I need to fix it.
I get about a mile from the parts store, heading home, and all of a sudden the exhaust starts popping and belching. It's done it once or twice in the last couple of days but only under had acceleration. Truck didn't want to go above 30mph.
Little further down the road, trying to limp it home as I didn't have far to go, and the popping is worse, constant. Truck won't go above 20mph. Service engine soon light starts blinking, blinked maybe 9 times then stopped. Couple minutes later starts blinking again, maybe 11 or 12 times, then stopped.
Managed to limp it home, threw my code reader on it and pulled the following (less the P0328, I know about that one):
P0300 - Multiple cylinder misfire
P0301 - Cylinder #1 misfire
P0732 - A/T 2nd gear signal fault
Could the bad exhaust leak be causing this? I'm wondering (hoping, dang near praying) that it's because I did more driving tonight than I do to/from work. I'm thinking that with the engine running hotter due to the longer drive, when the engine leaned out from the higher operating temperature, that coupled with the lowered back pressure from the exhaust leak, it just didn't want to run and started misfiring?
Any truth to my hopes?
Could I have damaged anything tonight?
Is there a chance my timing belt is shot?
What can I do to find out?
