You should get o2 simulators, ive seen them on Ebay before, they send back the correct amount of voltage to the computer, basically "tricking" the computer into thinking a Cat is there. I dont know if those really work or not Ive not had any experience with them, but my friend put those on his car that should have a Cat and it runs perfect, just a thought.

 

I know this is a late response to the red headers but ive always thought it meant there was too much oxegyn in your mixture.

 

i need to know were the crankshaft position sensor is i replaced the coil and still no fix i can get the engine to start now it turns no spark the repair manual says to check coil crank and camshaft position sensors and pcm

 

the crankshaft postion sensor is mounted on the passenger side of the transmission bell housing. it reads some grooves on the flywheel.
the camshaft position sensor is inside the distributor.

 

well... thats where it is on my ram

 

the book says it on the right side of the engine block but right from what angle in the car or in front of the car the 4 cyl is on the bellhousing not the v6 or v8 but thanks anyway

 

im pretty sure it's the right side as if you were sitting in your drivers seat.
