I believe I have narrowed down my code 52 to the ecu. I am hesitant to buy a used one and wanted to see if anyone had any luck with sending theirs out to be rebuilt? If so, who did you send it to?
Thanks.

Personally I'd buy a used factory ecu before a reman job. I've had a couple reman ecus go bad

I would open it up and look for corrosion, If you have some, used tv tuner spray, clean it all up then look for broken solder joints and repair those. There is not much in these dinosaurs. I had same problem, found allot corrosion and broken solder joints, repaired myself.

Disclaimer
My truck would not run at all, i used a friend ecu to confirm mine was bad before starting such a task, I had nothing to lose and everything to gain.

I have had good luck with ECM Depot out of Texas .

I think @ $300.00 with a core

Good Warranty unless it gets water damage .

Other than the case being corroded, I have no idea what to look for but it looks ok to me?

Other then a Turbo truck I have never seen a non turbo computer not fail unless it got wet. I would take my chance with a used one. I was unaware that you could get remanufactured computers but a truck I bought awhile back did have one in it that had a reman sticker on it.

Mine looks the same inside but obviously has something wrong with it,put it I my buddy's truck and acts exactly like it does in mine.oh well

What is your truck doing? Are you gonna get it rebuilt or get a used one?

-Random miss
-Erratic CEL ( no pattern to blinks)
-Timing pulled when miss happens while watching with timing light
Took a buddies running 86 22re and swapped out plug wires,cap,distributer,AFM,TPS,coil/igniter.All one at a time and nothing changed until I swapped in his ecu,now with his ecu it runs great with all my original parts still in place .no stutter ,no cel.Now his runs like crap now with my ecu in his truck.ha ha

Sounds like you do have a bad computer. As far as Check Engine Light that comes on intermittently with no codes, in my past experience it is due to some vacuum leaks. I would replace the vacuum lines if they are old and brittle.

runs great wit my buddys ecm,vacuum lines are all tight and pliable

Mine had allot of corrosion around the transistors attached to the housing and around the input pins going to the board.

dzldust

Mine looks like new inside but after cleaning contacts and looking closely at everything it still is acting up

Well I put a remanufactured ecu in and the code 52 is still there. Bummed.
