Well just want to say I finally got it figured out, thanks for all the help from ECCS to get my other problems figured out it turned out to be a bad reman opti-spark so I ordered one from ECKLERS Corvette which was new and was a billet version. It runs like a dream finally !!!! Thanks to...

Ok so I found the ASR Adjustment and did that and then rechecked the TPS Voltage and Percentage and they are now at .68 volts/0 % closed throttle and 4.45 volts/99% wide open throttle. I hooked a timing light to each plug wire and it flashes great until the stumble starts. When it tries to idle...

Ohm results on the Injectors are 12.1 the lowest 12.3 the highest on a cold engine. The TPS voltage goes to 2.90 with foot to the floor and show TPS% at 68 with foot to the floor.

Yes when it first starts it runs very rich almost like RAW FUEL smell out exhaust. I had it running trying to go into closed loop and started to smell something getting hot ! and I used and infrared gun on the Catalytic Converters and they read almost 800 degree's so I shut it down ? If I keep...

Does it matter for the resistance test on a Hot or Cold Engine ?

Ok Will do that and post back tommrrow night. The TPS from what I remember goes from around .62 volts to 2.80 volts with the pedal depressed all the way down. Fuel Pressure 42 PSI on the rail and I didn't see much bleed down until about 10 mins after. One last note it is very rich on initial...

This is Data Log from After the Fuel Pump Sock Replacement/Fuel Filter and Fuel Treatment. I have not got to the throttle body cleaning yet, and gonna do the timing light test on all the plug wires tomrrow maybe this will shed some light on the remaining issues. Thanks ! On question what does it...

Will do the throttle body cleaning in the am and the fuel system clean and pressure test. Great idea about the timing light never thought of that. I will print out a data sheet from my scanner and post it when I get off work tommrow. If I remember right the LTFT were both around 128 but I could...

Well got it back together with the correct CalPack/PROM from Zip Corvette. Now it starts and kinda runs but I can now read codes and Data from my scanner for the first time in 2 1/2 years !!. It wont idle now and feels like a misfire but when you give her some gas it smooths out ? I replaced the...

Okay great !! I found an EPROM/CALPAK and will order wont be here for about 7-10 days then will post back with the results and go from there, can't thank you enough for all the help !

Here are the pictures of the PROM The ECM #'s on the ECM that run the car 16159278 ECUEA183 The ECM#'s on the ECM that don't work are 16138461

Ya that looks exactly like what I got those letters from

Yes that is the code on top of the rectangular chip on the assembly that is what came back with the ecm when it was rebuilt. Maybe they screwed something up ? I will take a picture after work on post to make sure I'm reading the right stuff.

OKAY with the EPROM installed it starts and runs but stumbles and security and sys flashing and service ASR is on when jumpered pins A & G together I get C12 C41 H41. Same result with the EPROM out of the ECM. except for the C12. When it does stumble it sounds like the relays are clicking on...
