HairyCanary said:112* definitely is narrow enough to cause some idle issues. Mine won't come even close to idling properly (my LSA is even narrower, 110*) without the TwEECer. It takes a pretty substantial vacuum leak to make it idle badly.
As for sound -- definitely expect it to be a bit louder, that's normal -- but not "no muffler" loud.
I'm betting you'd really benefit from a chip or tuner.

red94fiveo said:OK, I went home today and messed around with the car a little bit. I think I found a couple possible sources of a vacuum leak. The Orange tube on the tree that used to be hooked up to the smog was not hooked up to anything, so I plugged that. And a vacuum line from my intake to what I think the wiring diagram called the 'solenoid purge canister' had a big gash in it. Unfornately when I was trying to remove the vacuum line from the canister, the plastic fitting on the end of the canister was really brittle and it broke off, so I just plugged the end of the canister and the end of the vacuum line. The car still won't idle, I looked at my cam card and the LSA is 112.
Also, It sounds like a freakin grand national car or something, it seriously sounds like I am running with no mufflers or something, WAY louder than it was before. Any ideas about this? I will be ordering the FP gauge from steeda on monday, and I suppose I will go buy a new purge canister from ford. I couldn't drive the car to see if the power was any better today, b/c it is pouring outside. Thanks again for all the responses guys, I'm getting a little frustrated, but I'm going to stick with this one.
Check locally, there's gotta be a shop that burns chips. You could probably get away with a mail order chip on a N/A combo, but I don't know enough to make recommendations.red94fiveo said:What are some good palces to get chips from, at this point I would be OK with just doing that.
I'd be surprised if you saw much (if any) effect on power just because of a vacuum leak, especially a small one.As for the vacuum leak I was wondering about that more with the loss in power than the idle,
I bought and installed the TwEECer before doing my mods, so I didn't have a chance to drive it without. But I did try starting it with the TwEECer turned off. It wouldn't even come close to idling, it hunted between 300 and 2000 RPM a few times and then died every time. The GT EEC is not at all tolerant of aggressive cams.I don't think the vacuum leak would effect the idle, either. Did you drive your car at all before getter the twEECer? What did it drive like?
red94fiveo said:Ok, this just got a little more wierd! I just verifyed the timing and drove the car for the first time. The timing was at 18*, so I set it back to 13*. Oh, and I adjusted the idle screw on my TB, and now the car will idle pretty well, it doesn't die!
Anyway, I took the car out and at about 1/8 throttle it feels normal. Pressing the gas down anymore than that and the car just does nothing! I could pass it 10 times over in my Acura! I'm thinking that maybe its fuel related. I'm not even going to try to solve the problem until I get my FP gauge. Does this sounds fuel realated or do I really need a tune or both?
HairyCanary said:Does nothing? Stutters, dies, ?
'nother idea -- double check that all your plugs are firing correctly. Hard to believe, perhaps, but just having one plug notfiring can really make a 5.0 run like crap.
That's probably a good idea -- if I'm reading other posts correctly, you installed an adjustable regulator without a gauge? No way to tell, it might be way off. I can't remember how much mine needed adjustment, but it definitely wasn't exact. You want 39 psi.red94fiveo said:I'm not going to mess with it anymore until I get that FP gauge later this week.
94DreamGT said:Man Mark...you are not doing much for my confidence in getting my car running. I am installing heads/cam this weekend and was planning on driving it the next couple of weekends...I'm hoping mine doesn't experience the problems you are having.
BTW...I have a TwEECer on my "to get" list, but not until the end of the year. My FTI cam has a 111 LSA, so it might be an adventure, but as long as I can get it from point A to B without dying every second, I'll be ok.
