Hey guys, i seem to have a strange problem with my right exhaust. It only happens after a cruise where the car has been used for a while and the exhaust seems to want to push something out as if there is something stuck in it?. Feels sort of like its misfiring, but i have done all the usual checks (coil packs and connectors) and im certain it isnt them. Any ideas ?
Are your exhausts independent of each other? Also I get the same problem due to a corroded injector connector on my left cyl bank. food for thought!
It's possible that the cats are starting to block up or as mike said, there may be a loose baffle or packing inside a muffler.
