1998 sl1 143+ miles.
2 days ago I hit a bump while driving in the rain, shortly after I noticed a rattle/thumping noise coming from the rear end of the car. Turns out the strap to hold up the muffler had finally given away.
a day later(yesterday) the service engine light came on. I went to auto zone and p1404 was the code. The guy suggested cleaning the egr valve and strapping the muffler back up(obv.)I know about the egr valve and what it does, I just need some direction as to where and what to do.
im thinking it could be the fact that my muffler fell and loosened a connection of something. Also my car has a problem while idling the rpm's are sometimes at random, rev really high about 2500. Idk what to do!
i just got my oxygen sensor fixed about a month ago and a few other things( non related) and spent around $800.
the last thing I wanna do is spend a hefty amount of money that I don't have and is this something I can fix myself?
if so, how? I am fairly new to car mechanics, but am sure I could accomplish this petty task.
have the same problem?
