Alright.... don't have a book for this car. Bentley recently released the CD-ROM edition, but I'm holding out for the actual book format. Anybody have the CD?
The 1551 reports that cylinder #1 is misfiring quite frequently; car runs like crap; exhaust smells of raw gas.
1551 does NOT report any error codes.
Check engine light is blinking.
Remove the harness connector going to the cylinder 1 coil pack and there is no noticeable change in engine speed/sound/etc.
Test for spark on coil pack #1, no spark. Use same test on pack #2 -- Spark. So my test is ok, and I don't have spark on pack #1.
Swap pack #1 and #2. 1551 reports that cylinder #1 is misfiring... remove connector from cylinder 1 and get the same results as before. Just for ****s and giggles, remove connector at coil pack #2 (which was just swapped --- was installed in cylinder #1 position), car runs much rougher and idles much lower... then died)
So... at this point I know for a fact that the problem is lack of spark on cylinder #1, and I know for a fact that the coil packs are in proper working order.
Test on the coil pack harness connectors:
pin #1 on numbers 2, 3, 4 pack conncetors measure about 130k to ground. On pin #1 of pack #1 harness, I get about 9 megs or so (can't remember for sure now... damn! It was something rediculously high as compared to the others)
pin #2 on all of the connectors measure 0 ohms to ground... so they're all tied to ground
pin #3 on all of the connectors measures +12v (+14 of course when the car is running)
Having some trouble (again, the manual isn't available yet) tracing the wiring from the coil packs (pin 1/control leads) back... I figured they would lead to the computer, but they don't seem to (which I still don't believe)
Definitely can't find the same color coded wires at the computers harness (very few of the wires are even the same gauge)... but another problem --- the colors on the wires at the coil packs seem to have faded from being exposed to heat at the cylinder head.
Anybody out there that has a copy of the schematics?
It's a '99...
Dark now, and I don't have tools over here (it's my mom's car)... hate to see her spend money on repairing it ---- looking forward to your replies.
