I had a very similair frustrating experience, granted it was a 93 t-Bird Super Coupe and it WAS a Mass air car. I changed SOOO many parts and took it to many shops, one of which was a Ford electronics expert and nothing!

I decided to sell the car after 7 yrs of ownership, it was just getting too old and problematic after while, anyway, the guy who bought it was a hotrod builder and he spoke to a friend that had a Super Coupe and told him what to do to get the car running.

it WAS A VACUM LEAK

Everything looked tight and you dint hear the leak anywhere but the steel collor that attached to the intake plenum coming from the intercooler. The guy took a screw driver and a rubber mallet and slammed the collor as hard a s he could a few time, the Car started right up and ran like a champ but i had already signed the title.

Check for any places where there potentially could be a leak and get them really tight. Usually when issues like this are bieng so difficult its a simple thing that gets overlooked.

Good Luck

Youre not running rich-- youre lean. Those little specs on the ceramic of the plug came from your pistons. Youre detonating. It seems you might need to address some fuel system issues. How old is the fuel pump? What size is it?

 

[toomanytoys]

Vacuum leak could definitely be a problem. Fuel pressure might not be rising with rpms. But if the car stalls at red lights, that could be the fuel pump or a filter problem. He needs to find the problem before he nukes the motor.

Opps sorry about that guys, always forget about the no MAF equipped cars. I still sya it's an injector problem. Did you disconnect the battery and let it sit to reset the computer. I ran 14 degrees and 2 degrees colder plugs on a 125 shot for years no problems. How big a shot are you running? Anything over 50 I think you need bigger injectors, larger fuel pump and a tune.IMHO

you can run 125 with stock inj and pump!

I'm not sure about the pump. The filter is a few months old. I had a super coupe too. A 35th anny. My name "thrty5thsc". I tryed to post a video but it was too big for photobucket. The only vac. lines I have connected are for the fpr through the zex box, the booster, the map and the canister. Upper and lower intake gaskets are new.

 

[cledusdtrucker]

bring it down sat i am sure there will be a few stangers to look it over for ya

 

[thrty5thsc]

I'll bring it down. I'm going to put a new fuel filter in it today. I need to go with a stock pump right? I'll start getting some prices.

 

[thrty5thsc]

Just put in a new filter. No improvement.

 

[toomanytoys]

This would be a good time to upgrade the pump. A 255lph is good insurance against going lean.

 

[toomanytoys]

Can you verify fuel pressure while you are driving? Maybe hook up a temporary guage and tape it to the windshield?

 

[thrty5thsc]

I have a gauge on my rail. i'd have to get a fuel line so I can move it. It may be the same size as the one for my nos nozzle. I'll look at it. Can I use a pump that big with speed density? I also have a stock reg.

 

[cledusdtrucker]

i have an adj press reg i will sell ya
and i will just take off hood and sit on engine while you drive around to verify fuel press lol!!!

 

[toomanytoys]

A 255lph will work fine with your car. The regulator keeps it in check. Speed density wont be effected. If you are going to spray your car and run it hard the last thing you want is a pump thats not up to par. Unless of course you are planning to replace the engine anyway.

 

[thrty5thsc]

Right. I would like to put a nice engine in it but not right now. And not because I blew it up. I think i'll go with a 255 then. Cledus, your a crazy dude. Let's do it and put it on you tube. LOL!
