So i recently had a code 41 vehicle speed sensor, because the speedometer cable came undone, i fixed that and now the engine is starting drive rough/stumble, the codes have been erased and the car driven around and no codes come up, i tried adjusting the tps to see if that would help but it didnt do anything

heres a video

I would get a timing light and see how your timing is. Sounds like you valves are tap tap tapping a little. should be 10deg btdc. at operating temp and idle. If it was a rod knock you would know it.

You'll love a valve adjustment. A lot adding and subtracting.

At toyota, an easy $600. If you do it yourself about $12 a shim + VC gaskets and grommets.

Not sure what these guys are hearing that would be ignition timing related...

Do you mean a code 42? Code 41 is TPS ..

so i spent the day figuring this out, timing was perfect

the issue was my coilpack was not firing on the #4 cylinder, so its misfiring,

in the process of getting a replacement coilpack and will report back :)
