You never mentioned that the CEL was on. You should get the code(s) read at a parts store like autozone just to verify why the CEL is turned on. Post the code(s) on here. They will start with the letter P and have 4 numbers, like P1234.

The scanner can clear the codes, but some places will not clear the codes anymore.

 

Reset the CEL. If it comes back there is still an issue. If it comes back, pull/get the codes and we can go from there.

EDIT: Sorry, PA asked the same question. Take PA's advice.

 

He mentioned the CEL in his first post. I figured it was because of the exhaust leak & also I figured we'd sort it out after he got the new flexpipe.

 

okay ill try to get down to a shop today, if not ill look for my dads code reader(even though i have no idea how to use it) =X, but when i was driving with the bad flexpipe, my CEL kept turning on, then turning off. It never stayed completely on

 

Update:
CEL turned off, everything's running great
