Hey guys,
Had the 2.5L rebuilt this summer, and got it buttoned up in September. I replaced all the sensors except for the TPS (original?) and 02 sensor, which was 3-4 years old.
Here in NJ, my MJ would have never passed the free state inspection (hole in floor, non-op e-brake, no fender flares covering 31"s. In time, that stuff will all be done. In the meantime, I need the sticker, so I took it to a shop that does inspections and they overlook most of that stuff. But not emissions. I had high hydrocarbons and CO%. The tech said "that's usually the 02 sensor," so I returned mine under warantee, and got another Standard Ignition 02 sensor. Bring the truck back and the numbers are even higher!
It runs/drives OK, certainly not smoking, but rich smelling when it's cold (which I would expect). It needs to have the TPS replaced (which I'm doing this weekend). With all new sensors, what could cause this? My buddy has an MT-2500 which he's bringing over to help me with the TPS adjustment -- will that tell the story??
If it helps, me and the engine builder were concerned about a little excessive oil consumption at 700 miles. He was surprised to hear that the CCV system has no PCV valve and wondered if I have adequate crankcase ventilation. I'm going to check vacuum on the oil dipstick this weekend too -- could it be related?
Hatin' Renix right now.
Thanks!
