I think he has a ICM issue, either that, or a CPS. Its getting warmed up, shutting off, winds down the motor, cools off for a second, and restarts. To me thats a ICM or Coil or CPS.

Ummmm....?? What's the TV cable, ICM, coil, and the CPS (crank positioning sensor?) ....I'm not good with terminology either. How do I go about checking these things? Should also be noted that when I picked up the car it would easily roach the tires. Now, when I try to do a brake stand and keep both pedals floored, all that happens is the engine winds up, but the car doesn't move forward till I let off the brakes. Then instead of going 0 to 60 in the 6.6 it used to, it takes about 12 seconds. Then  like I said, it goes all the way up to about 6100 rpms, and I manually shift it by letting off the gas and going back into it.

If you could let me know what those mean I'd appreciate it. Thanks!

ICM = Ignition control Module
Coil = Sits on top of the ICM and both provide spark
CPS = Crank Position Sensor
TV Cable = Transmission Variable Cable. Works in conjunction with the throttle cable to shift gears when you mash on it.

Sounds like you need to start with a good tune up, and work your way from there.

How do I go about checking the TV cable? What exactly am I looking for when I'm doing it?

If you look at the linkage on the throttle body, there are 3 different connections.  The bottom 2 are the throttle linkages.  On the top there is a single black connector.  That is the TV cable....If you follow that line and look back you will see a black "thing"....

That is what it looks like...

If have skinny arms and can see, look from the top down and you will see the top of the connector....

Looks like that....its a button....if you push it, it will unlock so you can adjust it....The easiest way to check it is to press the button, then push the cone that is connected to the end of the cable that the connector extends from all the way back in, you will hear it click....When its all the way back in, while still pushing it down, open the throttle all the way, then release the button, that is approximately the proper adjustment.

Ok, 2 questions...well three really.

1) Is there a simpler way of pushing that TV cable button? My hands are small but I can't find a place to wedge them in...even with the scraped up knuckles.

2) Is the crank positioning sensor and the crankshaft position sensor the same sensor?

3) Where is the CPS located and how difficult would it be to change in 100+ degree temps lol.

1.  You can rock the engine forward to do it?  Unbolt the top engine dog bone mounts and use something to pull it forward, or you could try a long screw driver?

2.  Yes..

3.  Its located on the BACK of the block, just above the oil pan, about center of the engine....just below the knock sensor....How difficult.....in 100 degree weather?  ....I wouldn't even attempt it....You can't get to very much very easily under the car in the back....I haven't ever tried on the TGP though...a 5spd you could probably do it.  It would probably be easier to attempt it while you have the engine rocked forward doing the TV cable....

I had a friend help me try to work on the car today. Needless to say we gave up after 25 minutes of sweating to death. He told me something interesting  thought I'd ask you guys. Have you heard of a torque converter SWITCH? Not sure what it is, and he's not sure where it was located, i.e., inside or outside the T.C., but he told me his Cutlass ciera was doing something quite similar and they had to replace a torque converter switch. I've never heard of it, but then again I don't know shit about mechanical stuff yet. Any thoughts? Curious, what are the symptoms of having a loose TV cable or a bad CPS? Just for my own knowing.

A TCC usually has an issue with it causing the TC to lock up and the car will stall coming to a light because its still fully locked.

With your issues, I don't think that would be the problem.....If the car actually moved, that means the TC must be working or it would just sit and stall to 6000 and never move the car....If its shifting really hard like you say, thats a vacuum modulator problem or a TV cable problem as those are really the only 2 things that a transmission can have go wrong unless of course.....eek....the trans is slipping way bad and on its way out the door.  How does the trans fluid smell?  Dark brown and burnt? I hope not?

I'm guessing TV cable or Vacuum Modulator.  Check the line that runs from the vacuum modulator (It sticks out of the front of the Trans, next to the AC Accumlator)  to the intake plenum, it could've fallen off, which would cause a problem.  Could be ICM or COils too.

Ok, well just how insanely tough are the coils and the ICM to change? I don't figure the coils are too terribly hard, but I don't know about the ICM.

Well, considering the ICM is what the coils are on....figure it out :icon_wink:  It really not that hard, 3 bolts, 3 wire clips, off it comes....

Thanks...I seriously didn't know that. Like I said, I don't have a map of where eveything is on a car, and that makes nearly every trip to opening the hood an overwhelming experience lol. Now I know how my girlfriend felt when I told her to show me where the engine was LMAO!

Its really honestly not that "hard" of a thing...
It would be even funnier to go and ask her again when you have the engine out :icon_eek: :laugh:

We used to be like OMG!!!!!! AND ENGINE!!!! FUEL INJECTED!!! AHHHH!!!! IT won't come out!!! !?!?!?!? #)(*$#)& :LJFD)(#@*&$ 893890 now its just a laughing matter and within 2 hours its ready to come out...

Oh and you would be SO amazed at how much easier stuff is to work on when you have no engine/transmission in the car :icon_lol:

Not that hes recomending to do that to change the coils or ICM. But it is fairly easy and straight foward.
