Hey guys, looking for advice, I’ve gotten to the end of the rope in a sense.
I currently have a 1997 eclipse 420a
I have the basic modifications on it: Cold Air Intake, Headers, Straight Pipe (spacers on the O2 Sensors to fool the system).
About 4 years ago the Engine Blew and put in a New 420a in it, but then I got into a wreck, and the car sat for about a Year, it was repaired. After the repair was done, I decided to take it to a tech to make sure the engine was still good, and they did a Compression Check, all 4 cylinders are at 170 steady.
I have struggled with a CEL for 3 years now, and shows random MisFire on all Cylinders…
I have replaced the basics, Wires, plugs, Ignition Coil. And started from there from what I remember this is what I have also replaced:
Crank Sensor, Cam Sensor, MAP Sensor, Timing kit, Fuel Injectors, Intake and Exhaust Manifold Gaskets, Throttle Body, Fuel Pump, Fuel Pressure Regulator, EGR Valve, ECM (3 times now), knock sensors
Most parts have been replaced twice or more since I took it to a tech and they changed everything I had and have checked most of the Electrical to arrive to that the misfire comes and goes only at idle but couldn’t find the cause of the issue….
So now I’m at a lost and not sure where I go from here. Other options I have been told is to Tune the Car… (not sure if that would be something to consider since the Car does not have a Turbo)
Need to add that a smoke test has also been done to make sure it isn’t leaking air anywhere and all is sealed
