when my 93 civic with a DX block and SI head is cold it runs fine but when it warms up it hesitates after i hit the gas. once it gets goin its fine but it stumbles alot until like 2K , i dont know why . it did this same thing when it was in my crx . i hear that when its cold the ecu makes its own settings but then when warm it reads sensors.. any way to "trick " it into thinking its always cold?

 

mmmm, you wouldnt want the ecu to think you are in open loop all the time....
Any cel's?
How's your timming?

 

You don't want to unplug any sensors, as your car would never go into closed loop, and will run like *** and get poor mileage/performance.

I'd find out what sensors are failing/improperly connected and fix them. If you don't know how to test sensors or read a data stream/use a scope, take it to someone that does.

Are you running the right ECU? Is it wired right?

 

right now i am usin a ls ecu cause when i plug in the dx ecu the prob gets worse.. car wont even stay on.. the only thing i notice is that my spark plugs are very black.. not oily but like the color and feel of charcoal.. every sensor in connected except one on the very back of the block where oil filter is, its like a rubber boot lookin one. also. where can i get a pinout for obd1 on the net? i need to make sure my map sensor is connected to the right wires..
