KA24E problems!

[nrmskate]

Okay, I bought a 89' fastback, I bought it for 300$.

When I first got it, the engine didn't crank nor run at all (duh).

But, after about 5 months of patiently waiting, I finally got a replacement engine with only 86K miles on it. nothing internally is wrong.

Im just going to throw out there that the gas in the tank is about 6 years old.

It also has no Res., no cat, or muffler, so its loud as $hit.

When I start it up, it wants to die right away.

In order for me to keep it running, I have to keep hitting the gas and keep it at about 2k rpm.

I do this for about 2-3min and it finally can idle at 1k by itself without me giving it a little gas.

My question is, could the gas be causing this? Could the exhaust seeing as it has almost NO back pressure?

If thats not the case, what is?

Thanks.

Bump, Anyone?

might be the air regulator? thats what helps a car on a cold start

i strongly reccomend that you put an exhaust system in your car before you start moving things around and changing stuff once you have the acr put together complete then go ahead and make adjustments.

dump that gas out and get some fresh stuff in there. the gas is most likely bad.

[nrmskate]

You think the gas is whats causing it to not start very well? Along with not idling unless I keep hitting the gas?

You think my Injectors are gonna be dirty after running the old gas through them?

Im gonna go fill up with 93 octane tomorrow.

Should I also get a full cat-back, or just a muffler?

Any other commentary?

I think the motor expects the backpressure of having the exhaust system set up on the car. It really doesn't matter what kind you get, stock is fine. 6 year old gas is pretty crazy. I'm worried as hell about some 6 month old gas I have in my 240 sitting in the back yard. Seems a little silly to expect your car to idle properly when it's not even fully assembled.

yeah stop running the car on that junk. drain as much as you can and get rid of it. get a good fuel flush/injector cleaner product, fill up with high octane, change the fuel filter and see if that changes anything after about 50 miles.

Like mentioned, the old fuel could definitely be your problem. That's cheap and easy to verify. The exhaust may make a difference, but you'll need one anyway. Might as well put a complete system on there so it's street legal.It might also be the idle motor or the idle solenoid sticking from sitting for a long time. I would run some 'seafoam' through the intake system. If done completely (tank, intake, crankcase), it will clean injectors, valves, lifters, manifold, throttle body, and idle system.
