View Full Version : knock/stumble when warm

car is fine when cold- warms up has a short of stumble hesitation knock whatever you want to call it every 3rd-5th second, if i slap the accelerator then let it idle the stumble seems way worse

timing mark seems to be moving around then jumping on the stumble/hesitation not sure if timing or dizzi related-possibly original belt

im hoping its a sensor problem

Check TPS operation is as it should be.

A common problem is faulty/temperamental ECU's on N13's so perhaps trying another ECU, in hopes it's a good one can help.
