When I do the ignition cycle to pull codes im getting 12, 21, 37 and 55.

21 and 37 blink twice, like it will go blink, blink, - blink. Then blink, blink, - blink.

Same for the Torque converter code.

Does this have some meaning?

The PCM will store the same code more than once.

 

the code 21 twice could be a 33 , if its an earlier model they were bad about not having a consistancy to the flashes and you have to watch close - kinda makes it more of a guessing game

 

ah crap i didnt get that you were asking why its blinking twice. I thought you just wanted the engine code. im retarded.

 

I really don't understand your logic, could explain a little more how you came up with 33 from the 21 code flashing twice?

Much appreciated!

 

is it flashing 21 twice in a row, or after other codes, if it repeats what you could see as being code 21 right in a row it could be a 33
the pause between the flashes arent always the same gap apart, even if its on the first digit, especially the 95 models with the smaller PCM
2 flashes, a slight pause then 1 flash, could be just a 3 instead of a 21, then youll have a longer pause, then 2 flashes, short pause then 1 again, giving the second 3 to 33, but the short pause in the middle makes you think 21came up twice, ive gone through that confusion with my cars before. im not saying that is your code, or that your wrong, that could just be a possibility
95 models with the small PCM especially were worse about not having the pause between flahses all the same so it throws you off when watching for a code, i cant find the article i came across that explains it better, if i do ill post a link to it

 

you should jsut take it to one of those autoparts stores that will read your codes for free. then youll know if it is a 33..

 

do you trust people that will actually try for 10 munites in the computer to find you muffler bearings, lmao, i love doing that to new guys

most of them guys dont even know how to work those scanners and they tell you your PCM is bad when its just an o2 sensor

 

For some reason I think your right.

Reason being, my gas milage is perfectly fine right now, little over 40mpg with about 70% highway miles.

And code 33 is Air conditioning clutch relay circuit open or shorted (may be in the wide-open-throttle cutoff circuit).
That said, I took my a/c off before winter last year.

Racerx55, you have opened my eyes lol!

Thanks for the advise as I'm sure its refering to the a/c!
