94 hatch/lsv - back fire
Ok guys I could really use y'all help on this. Just bought an eg hatch it's lsv. Engine light is on. I've tried the paper clip trick and it didn't work. Here is what the car is doing. Cranks up fine and idles fine. If I gradually accelerate. It seems to hit a fast high rev limiter at about 3500rpm as if to be in limo mode. If I accelerate quicker it back fires pretty good and not wanna pick up speed until I let off accelerater and gradually accelerate. Any idea of what this could be. Thanks in advance

Not sure what ecu. Where would I see what ecu it is. And did it right. Tried using paper clip and tried using a wire to jump it. And just kinda visually inspected the connector and wires for damage or loose connection didn't see anything wrong. Someone was telling me if the ecu is chipped the paper clip trick might not work.

See diagram for 6th gen Civic I posted above. No have?
Do you remove the door sill molding? ECU only covered by carpet for 5th gen Civic?

My 5th gens only have carpet covering the ECU and service connector wiring harness. Both being Hatchbacks.

Very good. From here on out, I'll limit my mention of the kick panel to 6th gen Civics.
Must you remove the door sill molding to access or expose the ECU of 5th gen Civics? The OP needs to expose the ECU to photograph the ECU label.

On the side of the ECU should be a label with the ECU number i.e. P06-####
In the image that is a P28 ECU. The middle number is the ECU model number.
I think Ron had asked for your ECU model so he knows what he's dealing with.
Might also need you to open the ECU up to see if it is chipped. Means taking the bottom bracket off, then unbolting the ECU so you can unscrew the cover.
I believe it's the bottom right of the circuit board that has an empty Integrated Circuit (IC) spot if it's not chipped. A proper chipping has what's called a zif socket installed so you can pop IC chips in and out at will.
The spot is above a resistor bank, in particular R17 and R18. If you have a chip directly above this resistor bank then your ECU is chipped.

Just want you to know we aren't going anywhere and will still be here when you are ready.
