I bought an '88 Honda Civic 1.5 liter fuel injected hatchback w/4 speed tranny this week. The previous owner was told it suffers from vapor lock, but I don't think this is the issue the car has.

It can drive for up to an hour like a champ, and always starts up fine. But at some point after driving at least 20 minutes, it suddenly starts hiccuping, and hesisitating while cruising or accelerating. This gets more and more severe, until the car stalls out completely. It will start back up for a bit, but progressively gets worse until it won't even start back up. If its given time to cool down, it will start up and run like a champ again. I'm planning to check if its getting proper fuel and spark this week, but wanted check in to see if anyone else here has experienced this problem, and what the remedy was.

Her service records indicate that the distributer rotor, cap, and ignition coil was replaced in '02 due to customer complaint of "bucking." Six months later, she has a reciept from another shop complaining of "bucking" again, and they replaced the o2 sensor, plugs, wires, and called it a day. Then another shop diagnosed vapor lock, but she didn't have them fix anything. The ingitor was also replaced in '99.

I don't see the fuel pump ever being replaced, and it seems like I can keep the motor running for a bit when its trying to stall by spraying Carb cleaner in the throttle body, so I'm thinking of finding a fuel pump at a local junkyard, and trying that out.

Thanks.
