Motor is running a little rough. has a vibration feel to it while running 2200-2600 rpm. 2 spark plugs have dry carbon build up. cylinders 1 and 5. I have new pulser coil assembly, new coil packs, changed the oil, did sync and link, TPS showing proper voltage, switched out IAC, injectors tested and cleaned, vst cleaned, changed out both fuel pumps, checked all fuses, I cannot find any vacuum leaks.
The motor runs, idles a little rough, not bad though. I got high oil pressure last time out and the codes showing on YDS is TPS and Oil pressure sensor codes 39 and 18. I switched out TPS with a used one and dialed it in the correct voltage. I changed oil after seeing that code, haven't been on the water yet.
My questions are: What would cause High oil pressure? Sticky valves? What would throw a code 18 for TPS?
