So my car jerks and hickups on idle, also feels like it has less power hesitation on take off and bad fuel economy. I have been hunting and searching for solutions for 4 months.

Usual suspects were fuel filter and pump, vacuum leaks, exhaust leaks, bad coils, bad wiring harness, bad plugs and wires. Even wire positions and gapping to eliminate all ignition issues.

So i systematically went through all parts and finally landed on post earlier saying that the car is very specific about plugs.

So i bought bosch brand and that seemed to do the trick.

So i guess if anyone else struggles with these mysterious issues and can't get no reading, the plugs might just do the trick.
