ok, ive had this problem for almost a year now and i need to fix it, so I'm going to try again.

ok, it started out i bought this car and swapped my d15b2 in to it from my last civic everything went well on the swap besides when i started the car and tried to drive it, when i did under light throttle(<1/4) it would cut the gas then give it gas over and over again trying to idle while i was driving, so i tested everything with no results, it doesnt have a iacv or idle controllers, this went on like this for 3 months, until one day my friend with a integra let me barrow his ecu, the problem was a lot better now it only did it <1/8 throttle, and i could drive it at highway speeds no problem, so for the next 3 months thats how i drove it.

then i swapped my cam for a d16a6 cam, and suddenly the integra ecu wouldnt work anymore, so i went back to the d16a6 ecu the problem was full on back, so then i did what anyone would do i switched to obd1 and chipped the ecu and dynotuned it, but couldnt get rid of that ****ing problem, after testing the tps again, somehow before i had missed that the voltage changes with the engine on, so after trying more tests i gave up and masked the problem again, i blocked off all the air passages and used the throttle plate to give it enough air to idle, so im back down to <1/8 of terrible gas pedal, so i had been driving like that for 1 month, and then the unthinkable happens i started my car to leave work and now it does it at any throttle position, but i work 20 miles from home, so it took me about 20 minutes but i figured out that if i cut the tps ground it was like it was earlier that day, so i drove on my ungrounded tps fine for 2 weeks, and then i pulled off the highway and it goes back to doing it at any throttle position, so now i try everything possible on the side of the road, couldnt fix it, so i drove to my friends house about a mile away(having to keep engine rpm below 1200) and the only thing i could come up with this time was connect the reference and signal together i did this by using another tps and soldering the wires inside...

but i am stumped, i have posted before but not with this much info on this poblem, it is not a engine sensor related problem or computer problem since at one point or another i tested them and tried other known good parts or replaced them in my obd1 conversion, i think there might be some sort of voltage regulator somewhere, but i have no clue, i was also thinking eld, but im not sure, i used to throw that code, but i have it turned off in my ecu now, any help anyone could give me would be awesome, i didnt give you any info on the car yet so ill do that

its a 89 EF hatch (used to be dpfi) with a d15b2 block with arround 30,000 miles on it, a commetic sainless HG, a d15b7 pm3 head with a d16a6 cam(valves float bad at 7000 rpm), its ported and polished, a d15b7 intake with the obd0 injectors, and all the idle controllers were removed, it has 98 hp the last time i had it on the dyno (dynojet), and was chipped and tuned by me in chrome

 

Bump

 

No one can help?

 

if it was DPFI you had to switch 2 wires around..my buddies car was doing the same thing and thats what it was. i'll get the info when im off work

 

All you do is switch the outside two wires...

After swapping the two,the order from top to bottom
is yellow/red/green..

 

 

Yep I've done mpfi swaps before thank for the thought though

 

Anything else? I was hopping someone could have pointed me to a voltage rEgulator by now but I think it's accually regulated by the ecu with those 2 wires the wrong way the problem is more strange but this harness I'm using I used in my last civic no problem, and since all I've done is soldered all the connectons and it did the same **** before and after

 

never found the problem, scrapped the car, sorry
