I’ve comment on your videos before. I’ve got a 94 that I️ totally rebuilt. I skipped the opti because it was just done before I️ bough the car at a GM dealer (to the tune of $3500!!!). Everything ran fine up to a point but the car ran like garbage over 5,000 RPM.
Long story short, I️ did the LTCC semi-conversion. It solved everything. The car revs with zero issues and makes power to 6,500 rpm. The whole thing was fixed for ~$600.
I am dealing with the same issues with my 25th. Had to charge it jump start it 5 x to get home. Thanks for your videos. I'm going to watch them all.
Glad that is sounds like you found the issue. Can't wait to see what's causing it!
Mine was my coolant temp sensors
Not being able to rev like that is likely a very dirty air-filter or a plugged up catalytic converter - I had a cat plug up because i ignored a misfire for too long on my C4 - sounded just like that :)
Dan! Great to hear from you! I could have used your expertise as I worked with the PicoScope the last few months!
Good Monday morning on this Columbus day Biff... trouble shooting can be challenging.. do you have a check engine light on?
You too! No CEL, no DTCs tripped, but good news…I found the issue and will reveal it in the next one!
@@FearlessMods excellent 👍... LT1 engines run great when they are 100% ... Any misfire or lack of power without a check engine light.. that's when the head scratching begins...
Plugged exhaust?
🙊 where have you been for the last 10 years?!?! 🤣
Time for a 24x conversion ?
Jon, I don’t follow???
@@FearlessMods its using a LS1 computer and getting rid of the opti....never heard of it ? There are 2 companies that offer kits .....check it out
@@FearlessMods "torque head" coil on plug conversion as jon said turns lt1 into ls ignition and ob2 thats easily tuned and able to be read
