Need some help with misfiring
 

I'm lost with a few things ???
Ok here's the deal I just put a new motor in. I used my original head that I had rebuilt because of a broken timing belt. Then I let my sister drive my car and she blew rod threw the block . But anyway the car runs and drives but, it's shows multiple cyclinder misfires on the scan. Would the timing being of a tooth or two be the cause of this misfiring and running like poop? Also the white wire with a red stripe off the upper oil pan were does that plug in to. It's a single male square plug on the end I can't figure out ... I'm bashing my head off the wall trying to figure this out ????

you might need to replace your coil packs for the misfires.

Already tried that:-/

pull the front off and verify the timing. could be cam position sensor, but that should throw a code. could be a vac/MAF problem, but that should throw a code

no codes? ...check spark plugs? gap....

When you drive it will it go past a certain RPM or speed? A timing issue definitely sounds like a good possibility. I would pull the front off and check the timing for sure.

compression test

My A4 has a misfire as well. Checked the coil packs...they were fine. Mine gave off codes
P0303, P0299 and P0011. Any help would be greatly appreciated! Thanks
