Re: TOP END REFINISHING
I'm not exactly sure of what you mean by "singing ckt TPS". Are you hearing something or reading something electrically near the trans?

When I un-hook the power to the tranny control module, it does NOT happen. The shop that did the tranny said it was probably a shielding issue, related to Fluid Pressure Solenoid. Pffft. SOMEthing in the install in not 100% correct, but again, no trouble codes in the programmable tranny controller. It even calibrates for 0% TO, and 100% TO, in it's own Setup Wizard, on the handheld interface for the controller. Probably time to let this thread drop; maybe resume the 'Hesitation' thread 1990 Throttle Hesitation, FROM which Darryl chopped off for THIS thread... Top end is done - pretty sure it's done right (except for getting the TB to Marc, and re-installed).

Re: TOP END REFINISHING
Did you find your solution for the idle issue?

Re: TOP END REFINISHING
No I did not Billy (although it's not an 'idle' condition) - it's an issue that manifests @ 1.6 - 2.4% TO.
Marc H said the 'lope condition' that comes in @ 1.6% TO, and that continues from 1.6% - 2.4%, is a condition that "ALL 7,000 LT5's have". I don't agree, but he knows more than me. So until I can properly read AND write to the memory & calibration module, the 1.6 - 2.4% TO glitch is still there. Kind of a bitch at in-town driving / low throttle. But I know that all else is clean and in good burn order... And the 2nd TB block when removed put back in about a 75 rpm swing, in DM, that was not there WITH the block. Block made rock steady 675 rpm's Open and Closed Loop. When I get the hang of coding, I'll put the block back in to eliminate air leak in the TB 2nd holes, which is really negligible, as far as tuning.

Re: TOP END REFINISHING
I used CPU heat sink paste, used a finger to coat thin film over entire surface, torqued down in three steps, cleaned excess at margins with a q tip. Idea is to transfer heat from heatsink surface on underside of ignition module to plenum. Covering entire heatsink surface is the goal; can put on too little with result of incomplete transfer of heat resulting in hotspots with potential to burn out IGM, but too much only squeezes out excess when torqued. I play around a lot with electronics and ham radio. KC4NWF

Re: TOP END REFINISHING
I got a 20 grams container from Amazon for about 10 bucks. Will last me a lifetime.

Re: TOP END REFINISHING
Been using Bosch 4503 Platinum/Iridium with 4 prongs. Didn't think that that I would have to replace them until I got the PCV tube leak; fouled them.
