Ohk so ive spent the last week reading every thread about rough idle. ill fill in the blanks with my situation.
driving along the hwy and my temp gauge was not reading correctly , radiator cracked , dropped all the coolant, car lost power I free wheeled to edge of the road. let the car cool down filled with water really rough idle and blowing &$%^ loads of smoke. anyway RAA back to the house where I spent the next three days getting down to the head and replacing everything that I touched ie. all the gaskets head bolts cleaned everything new plug leads etc.
BTW : once the car pick up 500rpm she's all sweet.
My mechanic friend said that it could be the harmonic balancer giving it a rough idle:/ ?
also more info when I was doing the head I allowed accidently a fair bit of coolant to drain in to the exhaust manifold. but I assumed that it would just get burnt up perhaps this had effected the O2 sensors ? or even blocked the cat. (I &$%^ HATE EXHAUSTS BTW)
now one fully put back together the car idles rough I initially thought it could be left over gunk or coolant still to burn in the system. I ran and bled the cooling system correctly flushed the new radiator and yet the problem persists. I jumped on the internet read every forum I could, I checked all vacuum lines and replaced a couple that where leaking not I cannot hear anything and I sealed everything just in case. I then went to the coil pack tested the original one and then wacked on another that I had lying around and yet the same thing goes. I then went and cleaned out entire throttle body and plenum thinking could be that. I replaced the throttle body sensors both pintle valve etc.
I went around (while car was running and removed injector plug one at a time) and found one that when I disconnected the engine did not change its rpm or noise so I got excited thinking its stuffed injector so I then replaced with known working second hand job and now the engine does change when removing the plug but still has a annoying rough idle.
im lost now fellas this is where I turn to your help I have come to the extent of my knowledge and need help need the car running nicely by Thursday. PLEASE HELP ASAP.
