whats up guys,
i posted a while ago with 3 problems that noone could figure out. misfires, faulty tps, and system running lean bank 1 and 2. well, i have replaced all 8 plugs twice now, i ohmed the wires and they are all fine, i replaced both the o2 sensors, and now i replaced both coils. but the truck still seems to be stumbling/missing. it shakes (not to bad but noticable) when you step on the gas and the idle just dosen't feel or sound right, it seems rough. and to top it all off, now its not throwing any codes to check with the reader.

any ideas on where to go next? im open to any suggestion.

Also, what should happen if i unplug the TPS with the truck running, and what should happen if i start the truck with the TPS already unplugged?

 

Have you checked the cps? Crank position sensor....

Also have you checked for vacuum leaks?

 

and how would i go about checking the CPS? and wouldn't that throw a code saying it was bad? just a thought.
