I had my engine light come on a couple of times in a period of maybe a few months, and it had stuff to dow tih spark plugs "i think" both times gave me 2 same codes, knock sensor and the neutral switch code... but my car is 5speed manual not AT!!
Sometimes when im on the freeway , lets say at like 3,000rpms cruising it sometimes start jerking, kinda like bogging a little, sometimes its hard to notice, almost like maybe a fuel injector is disty and not spitting enough fuel in the engine and lets it jerk a little, ist weird.
I again replaced the spark plugs to new ones and reset my ECU and for a while it was normal but now it started doing that again, and im not sure what the heck it can be, i replaced the fuel filter, spark plugs, might have to check on the timing.
Has anyone had this problem or similar and were able to fix it or find out what it was maybe?
