It's been happening for a while now.
I get random jerks while driving on the freeway. Usually it's when I hit a small bump in the road - car starts jerking 4 or 5 times, then goes back to normal.
By "jerking", I mean the car feels like it loses power for a bit then gets back on, like the spark is being cut.
If I put it in neutral going over a bump, the RPMs dip & causes the car to stall out as well.
First thing I checked? Knock sensor. I replaced it with a different one, then I hardwired a resistor to the ECU wire. I get nothing.
Cleaned out my IAA with intake cleaner. Doesn't really help.
Checked for loose ground wires. They're all good.
For some reason my car like to misfire at idle as well, but it only does it half of the time. The car shakes back and forth and puffs out the exhaust like it was a cammed big block.
WTF is going on?
