I need help. I have a 1992 honda that has a jummpy tach, stalls out when excelerating but runs fine when you back off the gas. If you floor it it over fules and back fires. I have already done some things here is a list.
1.changed coil twice
2.changed dizzy twice
3.changed main relay
4.changed ecm
5.replaced grounds
6.removed pluged cat
I'm planing on changing the tps and testing the charcoal canister next.
I need some new info I'm getting stumped.

 

Does the check engine light or the S or D4 light start flashing when driving?

Have you checked for any code(s) stored in the ECU or TCU? Get a piece of wire or a thin paperclip to short a blue two-pin connector.

Copy and paste this into your web browser to see the procedure to get the codes: techauto.awardspace.com/dtc.html

 

RE 1992 honda .no check engine light and the car is a standard. there is no codes as well.

 

chk fuel pressure . also chk the gas itself, pour some gas in a container make sure that it is not contaminated cam timing ok?

 

Did you change the spark plugs? New distributor cap and rotor? Spark plug wires (I like NGKs or the honda ones)?

 

New plugs,wires,and two new distributers. I have looked up and tested for every problem befor replacing parts.I'm going to doubble check the timing and replace the tps. I took out the charcoal canister it helped a bit.

 

you said you switched the ECM for the tranny right?.... the tranny and ECM are matted 2geather from the factory. That COULD be why..Iv seen it happen when you swap around ECM's

 

The trany is a standard dose that still matter. It still does it with the ECM that came with the car. The guy I bought the car from did the work he did an engine swap. 11/1990 engine into a 1992. The tach is moving with the throtle now and the car is sputtring like the timing belt is out a tooth or two.

 

do you mean ECU? cus I was thinking TCU the tranny computer. But since your 5speed you dont have a TCU in your car just the ECU.

 

I think I wone the timing belt pullys all line up but the timing balencer is out one tooth. i hope this will fix the problem.
