87 Accord - running problem with too much pedal

[Mark G Meyers]

This is an 87 Accord LX w/auto trans and 2 bbl carb.

It will accelerate nicely to a point, but if I push the gas pedal too far it will sputter, lose power, and the tranny can even disengage so that the engine revs high but the car don't go. Any idea what it could be? I have just changed both fuel filters, and done some carb cleaning running the engine and spraying carb cleaner (through the horns). The plugs and wires look Ok.

One thing I have done in this car's recent on the road history was to add, and then remove, an aftermarket fuel pump in line just before the carb. The aftermarket pump was probably creating twice the fuel pressure as needed (4-7 lbs).

It appears to me to be a fuel problem or carb. problem. I suggest that you go to a Honda dealership and order a fuel pump made for your car. If the new fuel pump does not solve the problem, you may need to do some more work on the carb such as installing a carb kit. You should also adjust the timing and change the points and adjust the points. Also--check dist. cap for cracks.

Points?
I didn't know cars made in '87 had points.

Added info:
I got a pressure gauge and put it on the fuel line (otherwise going into the carb). It looks like it can make 2 pounds of pressure. The haynes manual has a more elaborate test for pump pressure involving removing the fuel pump relay and shorting across 1 and 2, and I haven't quite exactly found the relay yet, or how to remove it. But, they say 2.4 to 3.4 is what it needs to show.

What I can't figure out is how this could have happened with my aftermarket fuel pump in line to the carb as before. It appears the same problem was occuring then!

Sounds like you have a bad tranny.

the throttle plate for the secondary is vacuum controlled, check for vacumm leaks, and also check the vacuum advance on the distributor

I don't usually trust after market items since they are usually made to work with dozens of types and models of cars. They may or may not work in conjuction with your engine and engine related parts. That's why I suggested that you install a fuel pump from Honda Dealership that was made for your vehicle. You could also order one from a junkyard dealer--they are on a computer network and can get one for you even if they don't have any wrecked vehicles identical to your vehicle on the lot.
