I don't know either, just kind of assumed they did. I haven't had to learn anything about the FI cause haven't had any problems with FI since a 94 explorer, and it was still under warranty. I think the SGII displays vacuum it so I assumed there's one.

Oriely's says I have one, and it's the same as the impala. Too bad the impala doesn't have cam position sensors. I should get a manual since I have 2 of these and plan on putting another 100k on this one, then hand it down to my son.

Best $40 bucks a guy can spend for a car. His or Hers! I picked up the habit from my Dad who had a Haynes or Chilton for every car anyone in the family or close friends meant to keep. He saved alot of people a bunch of money in repairs through the years!

I've never had a bad position sensor on any of gm's vvt engines, it always comes back to solenoids/actuators/chains/timing/oil level+pressure

Used to get manuals for bikes and cars, but last 15 years haven't had to do anything on cars that I need a manual and sold the bikes, been just the simple stuff like brakes and wheel bearings.

A few weeks ago swapped MAFs with KT's cobalt since it only has 26,000 miles, no change, developed an annoying miss first thing every morning when releasing the clutch to get it rolling. Getting P0101 regularly and occasional P0102. Last week when I got home I decided to take a close look at the wires at the MAF, took a little piece of electrical tape off the end of the loom, inspected with 5-6 wires and couldn't see any damage. Next day it did the high speed stumble 5-6 times. Been almost perfect since, no more CELs.

Debating liquid taping the wires but if I ever have to mess with them again it would make it difficult.

Kt's cobalt did get a CEL a few days later with my MAF, but she refueled and it came on shortly so I expect that's really the cause.

If you have to rework that connector you'll want to replace it as a pigtail anyway

Thanks, I just assumed I'd have to splice it together and didn't want to do that. Went searching and found new connectors with 12" of wire so I feel safe in liquid taping and maybe that will be the end of it.

Well almost, KT's cobalt threw a CEL so maybe my MAF is still bad.

Took me just over a year to get around to it but finally fixed my problem last weekend, car ran fin 98% of the time just occasional miss/chug, sometimes a pretty big series of chugs. Nephew gave me a MAF extension to cut up and $6 of connections the CEL is gone and not a miss in a week.

Next step making it a FFV.

I was 90% sure where the problem was, but was just a minor inconvience, and when the CEL was on it ran 99% fine. Plugged the SG2 into it last weekend and no MGP, AVE or GPH reading at all so I finally broke down and replaced the pigtail. Seems down on power but the butt dyno lies.

Ran into this guys site

2007 Chevrolet HHR

So I now have FFV HHR fuel map with same engine and tranny as my XFE and going enable it to make if FFV, if it works then KT's Cobalt. Today E85 might not be cheaper per mile but it will be again if at only the cost of tuner $100 I love the flexiblity. And he claims GM detunes the E85 to hurt it maybe the cost differential will be less the my current and previous GM FFV at 18%.
