Also, check your vacuum with a gauge. The lines may appear fine, but you can't KNOW if your vacuum is fine without confirming it with a gauge. Won't take you long and it may very well isolate the problem.

What was the exact temperature when you checked it and what was the resistance? Also, did you check it at a different temperature range? The more details you share, the more effective we can be helping you. :)


Using a Fluke 62 Mini Infrared Thermometer. My recollection back labor day weekend temp was 79 F @ 2.7 K OHM with engin cold

Agree, I'll try to check it again.

Special thanks to Richard Andrade his been very helpful.

I wanted to give a follow up. I had a shop do smoke test to find any intake leak. It appears the leak's coming out from the MAF air guide cowl rubber. We did not see any other leaks although the tech said it's difficult to be 100% certain that there were no other other with the intake in place. He suggested that the intake be remove and parts be replace. He also pointed out my hard start problem. He notice that the starter had a strange sound when cranking and it took three cranks to get my car running. He thinks it's the starter. I told him that I just replaced the start about month ago and the strange sound was coming from the missing teeth on the ring gear. Then he explained that this is the cause for my hard starting because the crank sensor did not get signal from the missing teeth on the ring gear which it looks for so that computer knows when to apply spark and fuel during starting.
His statement do make sense but I'm not a mechanic so not sure if that's true.

Should I replace only the MAF rubber cowl or just do the whole intake? I would probably have someone do the job I'm definitely worried that I might mess things up. Although I have done most of the maintenance on my car i.e.... TB, suspensions refresh and other repairs. If I leave the starter ring gear for now until the next clutch job what's the worst case scenario?
