Ok before I ask my question I would like to tell you a little about my car. Its a 90 civic std (model below the dx) w/ a 95 B18B1 motor. I have a 90 ls tranny (really dosent have anything to do with this but o well) and a 90 ls computer.

The swap is complete and runs fine (idle's a little high but thats a diff. story), but after about 4-5 miles the check engine light comes on. I took the ecu cover out and checked the peoblem. The light blinked 7 times (tps). I have already swapped out the throttle body, and it still comes on. After a little research I found the wires connectiing to the tps were mixed up. I fixed that and still the light comes on. Has any one else had this problem??? My dad seems to think it could be the injectors. Granted my dad is a old school muscle car guy he has been right about alot of stuff on my car. Should I use the 90 injectors instead of the 95 injectors??? Any help would be greatly appreciated. Thanks

I'll ask around.

 

sounds like when You swap a eclipse throttle body on a mirage. The tps sensor is getting more voltage than your old t-body so it is throwing your ecu off a little bit. to fix this problem on mirages all we do is swap out the tps it self to stock on the swapped out t-body. not sure thats your problem though.

 

yes you have to use the 1990 injectors. the 95's are obd1 (99%) and the 1990's are obd0 (100%). im not sure about this causing a TPS code but i know that you have to use those injectors if everything else is obd0

 

yea i get the exact same problem but only when i floor my zc. so to change it all i need to do it change the injectors?

 

ok so anyone have some 90 injectors???? Any one else have any ideas on how to get rid of this damn bright yellow light.

 

yeh my 95 motor had 90 injectors also

 

So your saying that having 90 injectors instead of 95 injectors will prob. get rid of the light???

 

im saying that is causing your ecu to read improper resistance from your injectors. you need obd 0 injectors, ecu, dist.

 

maybe its a blown motor
