Hello, I purchased an 01 Sportage cheap last summer. Needed a head, found a rebuild one on Craigslist. We have put approx 15k miles on it since. The other weekend just running down the road it made a pop and lost power. No start. When I got back home #4 plug well was full of oil. Still had 160 lbs compression or more on all cylinders. Found a place on the cam cover gasket where it fell out of the landing and was pinched out. Replaced Spark plugs, Cam cover gasket, PCV valve & grommet. Had 3&4 miss fire codes multiple miss fires codes. Cleared them, tried to start, no luck. Now I get P1121 and if I keep cranking code P1115. I never checked the coils for resistance, but I don't think coils would generate those codes. Could the TPS just fail going down the road. I had to stop working on it Sat. morning to go to a family thing so I didn't get to do any more diagnosis. Is it the Blk/Yellow wire from the TPS to check voltage? I read it some where but didn't write it down. I'm getting that CRS where if I don't write it down I can't remember... Anyone else ever have this issue? Ideas anyone? Thanks in advance!!
