ok i just installed pacesetter LT headers and y-pipe with a aero turbine muffler and no cats. it ran fine all day until that night i lost control of the throttle and the check engine light came on also the red lightening bolt that flashes. i pulled the codes with the SC programmer and these are the codes. p0016( crankshaft/camshaft timing misalignment-bank1 sensor 1) p0405(egr position sensor circuit low) p0344(camshaft position sensor intermittent- bank 1 sensor 1) can someone please help me??????

 

did it like rev up and down like it was redlineing. My did that when my camshaft sensor went bad. It happend like 2 years ago i think it was like a 2 or 3 hundred dollar (cant remember exactly) fix at a shop.

 

What year and engine. Important info missing.

 

I'm guessing there is a wire melted to your headers somewhere,almost the same thing happened to me after putting headers on a 94 chevy I used to have. I had an MSD ignition and MSD wires one of which melted to my headers and my truck started bucking and stuttering then it died, dash lit up like a christmas tree! Replaced the wire and shielded them all from heat really well and I had no more problems.

 

it a 05 ram daytona 5.7. and when it has the engine codes it idles rough and around 1500 rpm and i dont have any control of the gas pedal. but if i clear the codes it will run fine for about a minute as if there wasnt a problem but the codes pop back up and runs like crap. maybe it could be the headers melted some wires but not sure cus i dont see why it would run perfectly fine all day and all of a sudden get a problem. any other suggestions?

 

It only takes a minute or two for headers to get hot enough to melt wires again.

 

Yup, sending a signal to ground will drive a PCM crazy!!

 

Exh headers run what temps? 1600* +/-? It doesnt take much an anything to melt at those temps.......LOL

 

problem fixed!!!! the sensor connected to the transmission on the passenger side wires were melted and i replaced them and it runs perfect now. thank!!!

 

Good call Bluesmanjesse.........good call.
