Title: Type II coilpack
Post by: daveismissing on August 02 2011, 12:18:51 AM: What was the issue with using them (3 coil units)?
Baseplate is drilled differently?

Post by: Scoobum on August 02 2011, 08:27:31 AM: I believe an adaptor plate is required.

Hmm too bad- have one on hand.

Maybe I'm barking up the wrong tree, here's my symptoms:

Car seems fine otherwise , no codes,
highway driving-periodically above ~2200 it ....bogs hesitates.
backoff the throttle a bit and it clears up.
I do see a bit of black deposit on the lower quarters at the tailpipe.

Thoughts?

Post by: daveismissing on August 02 2011, 11:55:31 AM: I guess you guys are forcing my hand to get a PL.
So I wouldn't necessarily see retard if fuel disappeared?

This is the car with the new DW pump ( installed by ArizonaGN )

I guess that would depend on how much boost.

Post by: Steve Wood on August 02 2011, 04:05:45 PM: if you had powerlogger, it would be easy to see if the o2s fell at this time which would be indicative of lack of fuel, but, even with a scanmaster you can watch them and see if they change at this time.

Title: Re: Type II coilpack
Post by: Steve Wood on August 02 2011, 07:18:19 PM: also...crank it up, unplug the cam sensor and go drive it...see if that changes anything

Post by: daveismissing on August 02 2011, 08:50:16 PM: Thanks Steve. I'll do that and report

I would not be surprised. I have heard that some of the Delco sensors have been flaky lately....alth o I run SD on my cars, I use Denso sensors and they seem to be reliable/consistent. I don't like heated sensors.

Post by: Just a Six? on August 12 2011, 09:04:30 AM: Dave I have 3-4 low mile Denso sensors that work fine if you want to try one.

Post by: daveismissing on August 16 2011, 09:35:47 PM: Doing a visual over the car on the weekend.
I find the intercooler hose clamp right off, in fact its under the hose.
(wasn't me)
Seems to run better now for some reason...

Whats a good cross-count on a scanmaster?

Post by: Steve Wood on August 16 2011, 11:06:27 PM: 10-50 per scanmaster frame (about 1.4 sec)
