Wanted to borrow CAS (Saint Cloud)

[Jungy]

I'm trying to get to the bottom of my hesitation/misfire probs and don't want to go out and buy a CAS to find out it doesn't fix the problem. I would appreciate it if someone in the area could help me out, it wouldnt take long at all.

I have a spare 1G Cam Angle Sensor at my house in Blaine. Feel free to come try it.

I really appreciate the offer the only problem is that the car doesn't drive very well at all at cruising speeds because of the problems so an hour drive to and from Blaine isn't ideal.

Well I drove down to Rogers last night and borrowed Pat's (tehehodi) CAS to see if that was the cause of my hesitation. No change ... so I narrowed it down to be a fuel injector issue now and went down the line unplugging injectors one by one while idling and everyone i'd unplug would make the car stumble until I got to the last one and there was no change. I ohm'ed all the injectors out and all tested 5 ohms (Bosch 1600's), I don't suspect it to be injectors because they are new, now I am going to see if I'm getting any signal at the injector from the ecu.

Edit: No dice went out and tested it I'm getting about 3v at every injector connector at idle. I do hear a slight change in idle when I disconnect the #4 injector but not as much as the rest. Dead/clogged injector?

Are you on E85? 1600's are tricky injectors. From my experience, they don't work all that hot on normal pump gas. They work better when you start using E85, but are still a little tricky.

Are you running pump or e85? If you are running e85, have you looked to see if you've accumulated some of the mysterious black goo on your injector tips? If you are running e85, I'd personally remove the injectors and let the tips soak in a small container of regular gasoline for 15 minutes to "clean" them. Reinstall and see if you notice a difference.

But in the end, keep in mind that 1600's are just tricky in general.

Change #3 and #4 to see if the problem stays with the cylinder or the injector. That should help diagnose if it's electrical or injector related.

I'm running e85 and I'm getting about 3v at every injector connector at idle and each injector has a resistance of 5 ohms (bosch 1600's). I disconnected each injector one by one while idling and the car would stumble for every injector. I'm running br7es' and tried gapping them at .020, .026, and .034 none of which helped at all. Tested the CAS wiring and I'm getting 12v between the red and black wires, 5v between the blue/white and black wires, and 5v between the blue/black and black wires. This was all tested with the key on and the connector disconnected from the CAS and probing the pins inside it. Its definably something beyond injector stumble, I moved the car from my parking spot to my garage and at about 2200 the car was bucking and the tach had an electrical jitter to it. My wideband is pulling its power and ground from the ecu (pin 12 & 26) so I wonder if the heater circuit for it is drawing too much current from the ecu and causing these issues. I'm gunna rewire it to the cig lighter power and chassis ground it and if that doesn't take care of it I'm all out of ideas and I'll call Shane.
