1) The EFI fuse in in the engine compartment and all that's needed to check it is to see if the check engine light comes on with the key. 2) The coil pack bracket does not need to be grounded. Any engine that won't run without it has other problems. 3) Using a meter would go a lot further...

My point was a system charged without being evacuated can't possibly attain vent temps of 42 degrees...

Maybe I misunderstood but it seemed you were implying he didn't do that...

^ Indeed. I was just going to point that out. I'm unaware what the head is made from but it has to be one of the heat treatable alloys. The temperature required to anneal any of them (appx 800 F) is easily achieved on the exhaust side. The cooling rate has to be fairly slow and relatively...

Piratetip: You can't be serious...

Sheet of .032" 1100 series aluminum, tin snips, and a Unibit always works for me....

^ Amen. One he hasn't even gotten yet...

It can be done using compressed air or the rope trick. No head pulling required...

The O2 sensor has the least authority of any on the engine. That doesn't apply to only this car either, it's EFI 101. As was already pointed out the ECU will default to running the engine slightly rich with a disconnected or shorted lambda input. The behavior is mandated by federal emissions...

Shouldn't back out...has an O ring to keep it snug. Adjustment effect depends on whether it's a turbo or N/A afm since the screw serves different purposes on each. It's why the factory position of one is code stamped into the housing while the other isn't...

Note that my fingers never left my hands. I don't see where he stated the cable was broken. And it's way above 40 mph for TEMS. Thanks for chiming in though Grasshopper. And now, for my next trick...

Well, there ya go...

Just what it says. 42 means the speed sensor located in your speedometer isn't working or it is but the signal isn't reaching the ECU. Speedo working? Cable broke? If not run the cruise control diagnostics as a quick way to check the sensor. See the TSRM. 43 means the start signal isn't...

Obviously? No wonder you're having problems...

No offense there guy but you need lots of details for that? Open the hatch then bend over and look. I'm sure you'll be able to figure it out...

^ That car needs to be closer to the ground ;)

That'll tell you. Could always use a freq or universal counter too if all you're looking for is duration. Any worthy of the name will calculate period. Have fun...

That's a great pic Ian. From photos I'd always thought Ayers was too steep to hike. Good job. Better you than me though...I'm afraid of heights ;)

Kenny: The injectors are sunk (ground sided) so probing #30, #20, and #10 at or after they leave the ECU will work for pairs. Reference battery positive or any other part of the positive side. Or just go across the clips. If you have a current probe for the scope use it. It'll tell you a lot...

I wouldn't exactly call 2200 meters a speed bump. You've got that big rock out in the middle of nowhere too ;)
