well im back with a computer.

should this work? i also am now running a windows 10 platform which you mentioned worked out for you.

dave51 you also mentioned looking for a scope that listed specific automotive use, this: 8ch says automotive, though your suggested 6022BE says nothing specific about it.
Ill simply be looking for what ever I can use to get you the information to help me figure this out.


AWG, I had a video of flexplate examination, but it recorded in time lapse: https://www.youtube.com/watch?v=5LS1...ature=youtu.be you can slow it down to .25 play speed though its not very helpful. I tried holding a marker to where it would barley touch the plate while it was running. There is some flex that seems constant, not really sure what normal is. No visible cracks outside of crank mounting area.
Hopefully I can get better pictures of the shutters by removing the CKP.

 

I think I would measure flexplate runout using a dial gauge and cranking the motor with a socket, dont know what the acceptable figure is, but if it was anything more than about 0.020", I would be concerned

also read this code can be caused by a simple misfire issue, as the cam and crank loose sync for a brief moment...do you have any miss ?

out of interest...are you saying you swapped an entire wiring harness?...thats a huge job

 

I am familiar with the concept of a cracked or loose flexplate, but, are we really trying to measure run out ( lateral? axial?) with a dial micrometer? That's not in the fsm.?

 

The engine bay ignition harness has been completely replaced. I went through a donor and soldered/ rewired any issues. This was not the problem, but it did need to be done.


Watch "Flex plate windows" on YouTube
All shutters look good to me

In a new find upon removing the CKP there are no scratches, nor is it adjustable(factory intended).

Trying a new replacement Mopar CKP while the old Mopar CKP is out.

 

Yes, but I would get a couple of alligator clip cables instead of using those probes.




OTOH, the 1008C has 8 sets of alligator clip cables and the HT-25 ignition tester, as well as the automotive templates so I think it's a much better buy.

Yeah it's got 8 channels but I've only used 2 at time for anything. And if you wanted to test 6 ignition wires or injectors at a time (assuming it could handle that)(and I'm kinda doubting it could) you'd need 6 attenuators or current clamps or HT-25s and that would cost a ton.

Installed new mopar CPS just because i had one. old one was mopar as well, nothing changed from when I swapped them.

This idle is the same as it was before replacing. the oil pressure and voltage gauge will fluctuate with the rpm idle.

Does anyone have the mopar part number for the Cam sensor individually? perhaps napa echlin brand

 

watched the vid, but it told me nothin about run-out, as in checking a brake disc etc..with the dial gauge needle touching on the bottom of the flexplate

its been a long thread, but afaic, you have ruled out Crank sensor...Distributor should have been replaced long ago, so that should be out

leaves flexplate, timing chains.....or a miss..do you have irregular idle or misfire ?

 

what does a "miss" indicate beyond the aforementioned parts being suspect?


Irregular idle is just what the idle video is showing, constant bump in the RPM tact.

Ill see what I can do about getting a dial reading. Are you suggesting I take this measurement just above the teeth on the flex plate?

Thank you for your patience guys, the list is getting shorter. I'm a bit glad for the CKP not being the culprit as so many suggest on most every thread. My gut said this wasn't the case from day one and that's exactly what led this goose chase.

We are making progress!



i do have a front seal leak on the new seal from the engine swap. If i replace timing chain is there any recommendations? the donor engine is a rebuilt 92 lower 95 upper.

 

on something (flex plate) that is supposed to flex while running, is this not a valid test or are you being sarcastic?

I just want to get you all the right info so we know where to look moving forward. ill get a hf dial indicator if thats going to get us somewhere.

 

So apparently this code can be set on a vehicle that misfires, what happens is the miss causes the crank and cam to be ever so slightly out of sync for a very short time

I did not see the idle video, and misfire diagnosis can be difficult, however if you have that situation, I would be trying to rectify that condition

 

And the PCM is 1999?

 

But I don't think that precludes the possibility of 2 different problems.

 

Are you using 95 or 99 CPS(s)?

 

And for that matter, which pickup coil?

 

1999 original pcm, the donor i tried was from a matching 99.

1999 mopar crank position sensor and 1999 flex plate

1999 mopar cam position sensor with an aftermarket assembly
