Re: wont idle, raw fuel out the exhaust, breaks up above 2 grand, 450s+crome
its still in freakin limp mode! solid cel and i cant figure out why. ive tried three computers my chiped p28 my obd1 pr4 and my obd0 pr4 and they all show a solid cel. i was looking around the plugs checking all the wires because someone had an afc wired into it befor i got it by the looks of it and i just wanted to make sure all the wires had a good connection and i noticed that there are 2 wires that are cut... they are both on the center plug on the chassis harness. i looked in the alldata and in my manual and coundnt match up the colors for some reason. going off the numbers on the plug (top row 1-10 bottom row 11-20) there is a yellow wire in the 5th pin and a white and green wire in the 19th pin. what do these do? i looked allover and i couldnt find the other end of the wire? i cut the rubber cover off the harness as far back as i oculd and the other end of these wires are no where to be found. thanks for any help...i really want to have this thing on the road by the end of the week...

ok, turns out the two cut wires have nothing to with it. apparently xenocron found they arent needed and didnt put them in his harness. i messed around with it some today and finaly got a code 6 (ECT) out of the obd0 pr4. the other pr4 and the chipped p28 are still in limp mode. i reflowed all the solder on the p28 just for ***** and giggles but i really dont think that it did anything. i pulled all my charge piping out and checked every wire under the hood to see if i could come up with anything and nothing. ive went through a few pinpoint tests in the alldata just for the hell of it and nothing. i got the 450s working now, the car cranks and idles fine but dont try to take it past about 3-4 grand. im completely out of things to do...?

When you did your obd1 swap, did the car run fine with no codes before you tried to chip the ecu? Meaning with your stock 240's, stock p28 and that jazz did you have any issues? Or did you do the obd1 swap and then put your turbo setup on without checking to see if it ran first? It could be something as stupid as your main relay starting to crap out, or maybe your obd1 distributor's not wired in properly. If everything checked out fine first though, I'm kinda stumped on this one without actually seeing the car in person

all was fine, im kinda leaning towards going back with the obd0 stuff and sorting it out from there and completely ruleing the obd1 out of it. that seems slightly more logical i suppose. im about to the point of making a wire with a male pin on it and putting it in each plug on the engine and grounding it. then finding the other end of the wire at the computer and checking continuity on it to make sure all the wires have no breaks in them. i reckon thats the last thing to do?

where are you located? maybe someone on here lives near you and can look at it. it sounds like there are way too many variables to be able to troubleshoot this problem online. if you have never chipped a car before then there are even more. there are a lot of things that eperienced people dont really think about cause they do it a lot. also, what did the diesel place come up with on your injectors?
