A new "my lt1 runs like poo" thread :p

[KLAB]

Yeah I'm sticking it out with the opti till it is declared toast. Then I will do the efi connections conversion. But no need to upgrade now Yep its pretty scary lean but only at the top end like over 3k rpm. Strange, but I've been driving it the past couple days and taking it off the road soon to straighten it all out..

Yeah I remember checking that car out years ago and it's the one that set me on this train of thought.
Doesn't seem like a huge deal. Just need a nice accurate distributor with a locked out advance so I can control timing with the ecu, then use the conventional cap to distribute the spark just like an old school small block.
Pretty sure you can get a megasquirt to control fuel and spark now. Iirc he used either a fast or a dfi set up. But at the cost of those I'd just go efi connection lol.

Only big issue I see is getting the hole through the intake in the right place for the distributor.

Yeah i think he used a fast but megasquirts are great for the money. I believe there is a template online there is also a place that does them online for the thirdgen people I can't remember the site but it's lt1intakes.com or something it's been awhile.

Yeah, that sounds about right. I knew there was a place online. If the opti is f'ed I'm pretty sure this is the route I'm gonna take.
It's also the route I think I'm gonna look into for my turd gen if I stick with the lt1 I have for it.

If you go rear dizzy you have to drop the motor to remove it. I was going to go that route but after getting a lot og the ls1 stuff cheaper then off there site and really not liking how tight it is to work under the cowl anyway. I sed fuck that. And that's th e reason gm went with a front mounted opti in the first place. They actually have ltq blocks in some early 90's trucks but you can't telll unless you know what to look for because they ran a conventional dizzy setup. Anyway my point is either keep the opti and its issues. Or go efi and have tunability from a know and GREAT tuner. Megasquirt may be good for the price tag. But who will tune it? You'd be stuck tuning it yourself or paying someone more then a regular tune to do it for you. And that would negate the cost of the "cheaper" system as it were. I say check your lower opti vent hose the one soaked in oil and the one that probably fell off.

Trust me, I would have absolutely no issues with tuning it myself and honestly would rather. Tuned a number of carbe'd cars in my day with great success. Doing it with a laptop would be even easier.
Anyhow, if I stop being a pussy or it warms up a little this afternoon I plan to dig into it some today.

Anyhow, triple checked all the wires and connections. All was good. Also checked the lower vent hose, and while yes, it is covered in oil, it is still firmly in place lol.

Then I crawled under the nose and looked at the air filter. Tough to say if it's still wet but the mesh on it is definitely very rusty like it was soaked. So, I'll take it for a rip tomorrow and if it's still breaking up I'll try pulling the filter and see what happens
