it's the 80's I'd guess...

I've had trouble getting my 60's to idle correctly but Vince has done a great job although when in park my car idle hunts.

 

I've heard of a lot of people having issues with the idle on big injectors. but my car (still on stock injectors 2.4intake mani and a SRI) the idle jumps all over the place 800-1500

 

Interesting so you guys are also having idle issues in park (auto s/c) and also when at a stop?

 

I'm a manual NA, haha want to go supercharged

 

Im on 42's and I idle around 900 -1000,hope everything works out for you.

 

I have 60's and it idles funky too.Im manual not that it matters

 

mine only idles funky when in park... not when stopped other than a few random times.

 

Am i suppose to feel a tug everytime the car shifts at low speeds?

 

Anyone have any ideas as to why the idle is funky at a stop?

 

So you're not running the car on E85 right now?

Unless you have a vac leak or you're misfiring my guess would be your injectors.

 

Only running 91 right now.

Can't find any vac leaks, but as for the injectors like they are sitting wrong or what?

 

bad gasket?

 

All the gaskets are brand new thats what puzzles me.

 

Almost any build thread i've read about people using bigger injectors they have issues with the idle dancing all over the place. Give Vince some time to work it out

 

True, I'm bearly on mk II, I got mk III yesterday but the car wouldn't even run.

 

Vince can get the car to idle on big injectors. My car idled fine on the 60's and 80's I had in it. We'll recheck the injectors seat. Also need to recheck your plugs. They are prob fouled out by now from running so rich. find those other ones I told you about

 

Making the list of spark plugs on here to be safe;
NGK LTR6IX-11 (1 Step Colder - Iridium)
NGK 3587 (??- Double Plat)
Champion 470 (1 Step Colder - Copper)

 

NGK LTR6IX-11 (1 Step Colder - Iridium)
thats what I use, and they work fine.

 

Another question, have you changed your fuel filter?

 

Yeah fuel filter was changed a few months ago

 

Larger injectors in general have a hard time with idling. I'm guessing its due to the flow rate but I could be wrong.

If they weren't seating correctly that would cause a vacuum leak...which u should be able to notice on your boost/vac gauge. Also you'll be pretty lean under boost in my experiences.

You may want to double check with Vince but I'm almost positive you'll need a retune when you go E85...if so I would set the car up how you want to run it now that way you only have to go through this BS once

 

Jerry I'm running around 14s while underboost generally -10 to -20 ps . When I'm at wot I'm around 10.1 which is hella rich, 9psi as well.

 

Here's a update on the car;

We tested the TB and found no issues, then we realized that the L61 "flat" fuel rail was bottoming out with the SC bolts to the intake manifold so we changed it to an older Cavy L61 "round" fuel rail (similar looking to an LSJ fuel rail) and that clears the bolts very nicely. Then we were getting cylinder missfire codes P0300 so the spark plugs were done.

I had the same spark plugs for over 73K in the car and they were shot so they were replaced by autolite XP (they were cross ref with NGK LTR6IX-11) 1 step colder, taper seat, iridium.

The car runs better and the car now only dies sometimes at a stop/park. So now that all the mechanical bits are taken care of, its just a matter of fine tuning the idle/performance.

 

autolite xp is what I run

 

I think the rail makes it look alot cleaner too. Man were those plugs shot, and fouled. Hopefully the next tune will have a better idle. Once he leans you will enjoy the power. Im surprised how well it pulls already
