Every LT1 has opti issues :lol:
I know that reading is pretty far-fetched for most F-Body owners, but if you have problems with forums, you should try it out, if everything else comes out negative.
:biglaugh:
If you changed the plugs/wires and it was better…I bet you hit some sensor and it had shitty/loose wiring…
I would check that or find a LS1 STAT!
It was perfect for the 20 minutes that I was driving it before it got way worse. Fucking sensors. I’m kinda leaning towards a loose wire.
Plug wires are all seated properly?
Was it 20min or less then 20min? Some open loop/closed loop issue if the time was less to fully heat up.
Like I said, most likely a cracked wire on a sensor; either Water Temp or Air temp most likely.
Yeah, the wires were hugging those plugs like huge on Just Karter.
I don’t know the exact time, but it happened as soon as I pulled into the Carrabbas parking lot on the BLVD, and I live about 20 min away. So, 20 min, give or take a few.
Is it still on the original O2 sensors?
Yep. And the car has 80k on it.
This is why I’d like to find a scanner for it, so I can hopefully single out the issue before replacing first –> bitching later
hmmm LT1 … sputtering
opti
they make all LT1’s run like poo
Opti has been replaced.
I know a few people who have replaced optis a few times and gotten bad ones out of the box…not saying thats the issue but there is a chance…
this is why I hate LT1s
Not throwing any codes?
Yup… the crab-shell hi-voltage section blows… thus the reason to switch to a LTCC (Converts to a LS1 style ignition) or a Delteq (Lost spark coils; but I don’t think Delteq is in business anymore). That way the only part of the Opti you’re using is the optical wheel.
I have a scanner that does OBDI & OBDII
Ialso have 1 you can borrow that will give ya live data
pm LoudGp
When a symptom has 5 different possible sources, reading can only go so far. Opti-spark is a plague on LT1’s, have to do some trial and error, but reading is good for learning what to look for when you dig in.
I could scan it for you if need be.
still, even after the coil cause that definately needed to be replaced. hmmmmm have you checked fuel pressure?
