Thank you for the explanation! I am going to go check it out this morning. Thanks man, appreciate it.

Ok, it's a Performance Products 65mm throttle body for my '93. Where in the heck is the idle screw?? Trust me, I have felt and looked ALL OVER that TB and nothing. The directions show a pic of it...but I don't see it. Does anyone else have a Performance Product TB and can post a pic of...

Go to craigslist and post a wanted ad for the MAF sensor in the auto parts for sale section. You'll have 15 people offering to sell you their MAF for $20 within a couple hours.

I have a space IAC if you would like to borrow to see if it resolves your problem? Not sure where you are located. I'm in the Dallas area. Let me know.

Dude I feel your pain. See my post http://www.stangnet.com/mustang-forums/813098-help-please-no-power.html as it sounds very much like the same problem you are having. Agree? Whatever you do, PLEASE post what you did once you get it fixed. Let's get this figured out.

On my '66 with a 5.0 EFI from a '93 GT, I installed a b-cam to go along with my JBA exhaust, H-pipe, 3.55 gears and PI torque converter. The b-cam sounds excellent in my config.

I tested all four wires on the MAF connector. All checked out accordingly. Thanks for responding Joe. I was hoping to hear from you. Thoughts on what else it might be?

Will replacing the MAF correct error code 26 on KOEO?

Ok, I ran the KOER test. All I got was Code 33, which is EGR related, and I don't have EGR, so no real codes pulled at all. So what do we do from here? Again, this all goes back to the larger thread 'Help Please, No Power'. Any ideas???

No, not since before running KOEO. I'll run KOER tonight and post up.

I already tried cleaning it with MAF cleaner. Nothing. I couldn't find one to borrow, so I ordered a new one, just waiting for it to get here. I ran a test on all four wires on the oval plug going to the MAF sensor and all check out as they should. Should I run a KOER test?

Engine was warm.

Ok folks - if you followed my other thread labeled, "HELP PLEASE, NO POWER", well I finally was able to get my codes. Pretty cool I must say! Reminder, this is a '93 GT 5.0 EFI in my 1966 Mustang with AOD. KOEO Codes are: 15 26 85 84 I believe 84 is EGR vacuum solenoid circuit...

No you aren't way off. I just learned out to pull codes with a test light and am going to try to see if I can get them. I'll post what I find out in a seperate thread. Thank you!

How in the world did you figure that one out!?! I wonder if my issue is a cause of my JBA's. Read post called "HELP ME". Glad you found the issue, but that must have been a nightmare to track down.

Replaced the IAC and the fuel filter, same issue. Today I am going to replace the MAF. As I stated earlier, if I run the car with the MAF disconnected, there is no change in performance, so perhaps the MAF is the problem? Do my symptoms seem too severe for a MAF issue???

Anyone think the IAC or the MAF could be bad??? I unplug the MAF, but same condition. There was no change in idling or when driving with the MAF disconnected. I will give this one more week. In a week, I'm gonna yank all the darn wiring, computer, intake, sensors, etc. and go CARB. Seriously am!

"When you installed distributor did you have number 1 cylinder top dead stroke?" I believe so.?. If not, wouldn't it have driven bad the very first time after putting it in?

Thanks everyone for the help. Its SO frustrating. The issue is when I am driving the car and accelerate, it just doesn't want to go and it sounds like small popping or kicking, it's very hard to describe. Maybe sputtering? When I put in the distributor, it seem to drive great. No...

Well, the car starts great. Idles good. Revs good. It will drive fine with just a tad of throttle. I have timing set back to 14 degrees. If timing was 180 degrees off, would it still start good, rev good and still accelerate to speed (under little pedal)?
