2G 97 Eclipse GST help P0105 P0110 P0115

[FlyinRyan]

I have a 97 eclipse gst. I need help with please. The car ran great b 4up it started having problems. Its throwing codes. P0105 p0110 p0115. Car smokes black bad. Motor chugs. Hard starting. The fans come on all the time when car is running. They also come on and kick off if it don't start when starting. I do know that the o2 sensor wire broke off. Ran fine for along time. I changed the engine coolant sensor. Also swapped the map and mass with used ones. Still nothing. U guys have any ideas.

sounds like maybe wiring issue how long have you had the car? boost leak test do one, mainteance has it beend done plugs,wires, etc. fix the 02 sensor wire.

I have had it for a 1 1/2 yrs. Nice clean car. Plugs wires have been changed. That's what I was maybe thinking about a broken wire or so. Not sure where to start. Would a bad computer cause this. I heard they r known to have it go out.

Check out what each code is and means and start there. That always points you in the right direction

Fix what you know is wrong with the car first, The o2 sensor wire.

I had the same problem till about a week ago. check all your wires you might have one that grounding out. mine did and it start running good again.

What did you do exactly to check out the CEL codes?

P0105 & P0110 both point to the MAF, usually a bad or no connection on the 8 pin connector. My guess is yours has cracked/brittle wiring to it or you just didn't plug it in?​

P0115 is for the CTS (coolant temp sensor) which probably has bad wiring or is unplugged. This will also cause your fans to kick on ALL THE TIME, a symptom that you described in your OP.​

All three CEL codes you pulled will cause your car to run like ass, check the wiring and make sure both the MAF and CTS are plugged in. From what I'm reading in your post you didn't check anything out after pulling the CEL's off the ECU, take the time to do some research around here and you'll find the fix to the problems your having.

just for haha and giggles check the water senors for some reason that was a cause to my problems idk y

 

[FlyinRyan]

Where would I start checking the wires at if broke or grounding.

The other thing I forgot was when I bought the car. It would pull 17 lbs on boost. Later after I got it it would pull 14-15. It also cuts out at higher rpm . Like its starving for fuel. Not sure what's wrong

Did you do anything I mentioned from my previous post last week?
