It would appear to be a 1993 by the thread title but we do need a lot more detail really.
Single exhaust or dual system would be useful to know.
Thanks I missed that, but you are correct we are struggling a bit without more data.
I think that 1993 means Hotwire (fuelling by ECU, ignition by distributor) I also think it is on the cusp of being pre-cat, but it would be good to know.
I don't think this era had the carbon canister on the bulkhead?
I would still guess that overfilling might have caused an issue for the ecu, and it is not injecting to 4 of the cylinders. It doesn't sound like ignition (yet).
Also was the car refuelled recently , could it have been a duff batch of fuel with water in it (ethanol blends are susceptible to this) , or was the car fuel tank getting very low and it picked up some crud .
Sorry but we are really just guessing until we have more information.
