I looked in my Probst book and it doesn't have a valid reference for a code 89 for your year and model car. I haven't heard of a code 89 in a car without a computer controlled automatic transmission.not starting as easily again. did code tests and cylinder balance test again. koeo code 89 and 11. koer 11, cylinder test was 9. what is code 89 and how do i fix this one?

Do you notice the torque converter going into lock up mode?got me, i pulled 89 out of it 8 times on four different test cycles. my pos haynes manual refers to 89 as "lock up solenoid"?
after i got it running i took it for a drive, it ran great, gave it alot of throttle for the first time and maybe did a half mile total. brought it back and let it sit. all i get now is koeo code 11 five(5) times, koer code 11 two(2) times. no other codes. seems when it sits it thinks of problems to give me. when i do try to start it after sitting it acts like it is flooded, any ideas? thought it might be related to the nickel size hole i found in the mid pipe, passenger side. rechecked tps also and base idle is still around 600 - 700 (hard to put a number on it but quarter way above 500 rpm)
no, not really sure what that would feel like. apparently there is some sort of electrical part on this tranny that can be unplugged or go bad. will research that and se whats up. but i can't figure on how the tranny would cause starting problems.Do you notice the torque converter going into lock up mode?
The AOD auto trans in your car has no computer connection other than the NSS (Neutral Safety Switch). The NSS prevents the diagnostics from being run when the car is driven. Key On Engine Running test mode takes the throttle control away from the driver for several tests. This could prove hazardous if the computer was jumpered into test mode and then driven. In other words, the computer is completely ignorant of what the transmission is doing or what problems it may have.
AODE in 94 and later Mustangs used the computer to manage shifting, and will set codes in the computer. The 94-95 Mustang GT used a U4P0 -computer to control the AODE auto trans.
thats what i thought. never did get to look at it but parts stores have some sort of electrical "plug/valve" that they say "fits" my vehicle for the transmission. thought it may be there and causing problems. this is it:http://www.autozone.com/autozone/pa...yWord=transmission+solenoid&fromString=search
so i will keep searching for the cause of the hard start.
is there a tcc solenoid in the transmission that could be the source of code 89? i realize it should not cause starting and idling problems but it is another code i would like to not see back.Part Number: TCS5
Warranty: Limited Lifetime
Application: A4LD Transmission model this is for the 4 cylinder Auto Transmission. The parts lookup isn't much smarter or more accurate than most of the counter help, so beware...
Slow crank, no crank or cranks OK bit doesn't start?
Not unless you have a 4 cylinder car. There is no tcc solenoid on 5.0 Mustangs with an AOD.is there a tcc solenoid in the transmission that could be the source of code 89? i realize it should not cause starting and idling problems but it is another code i would like to not see back.
ok, just clutching at straws to get rid of that code. so the code 89 should just be considered as some sort of "phantom" code and ignored? just want all "11's" when i run the codes before i move on to getting it running 100% all the time.Not unless you have a 4 cylinder car.

Ignoring it is the only answer besides a computer that has lost its semiconductor mind...ok, just clutching at straws to get rid of that code. so the code 89 should just be considered as some sort of "phantom" code and ignored? just want all "11's" when i run the codes before i move on to getting it running 100% all the time.

Is this action more pronounced on a hot engine than on a cold engine?Sorry, just caught the last sentence here. Cranks and starts immediatly. Runs for a minute or two and then will just die. Starts back up but then runs terrible. Shudders and shakes and sounds awful and dies. This was the usual last week when i tried to let it run. Have not been able to play with it since. Throws no codes except that 89 (koeo) or the one for low coolant temp that goes away when it heats up. Once I restart it successfully, after the poor running restart, it runs flawlessly and will usually restart again flawlessly. Once again no codes ever except the two stated for koeo. Never any koer codes and balance test is always 9. This repeated every day upon start last week.
The PIP sensor inside the distributor isn't easy to test without an oscilloscope engine analyzer. It can and will cause strange problems.
From the Cranks OK, but No Start Checklist for Fuel Injected Mustangs - see paragraph 1 B
B.) PIP sensor in distributor. The PIP sensor supplies the timing pulse to trigger the TFI and injectors. A failing PIP sensor will sometimes let the engine start if the SPOUT is removed. See paragraph 5A – Using a noid light on the fuel injectors will tell if the PIP is working by flashing when the engine is cranking.
