So I still have a random miss fire and my truck feels like it boggs really bad. I have done the plenum, new distributor, cap, rotor, wires, plugs, cat, o2 sensors, and coil. I can't figure out what could be causing this issue. I did replace the crank shaft sensor and a little while after that I started having problems. I don't beleave it was a OEM sensor I put in. It was from napa. Do you guys think that could be it?

 

Yeah sounds like that exactly. Go oem for best relaiabilty. These trucks don't play well with off brand sensors and electronics.

 

What brand was the OEM sensors?

 

im thinking denso? might have to venture to the dealership

 

I had a random misfire issue... a new (dealership) CPS fixed it.
