I have owned my 86 Daytona for 17 years, I love my car. I have done just about everything imaginable to keep this thing running over the years but I have finely hit a road block. Over the last 6 months I have been trying to hunt down a problem that I had with the car starting and running fine while at idle but stalling once out on the street. After replacing several components (throttle position sensor, idle air control valve, and fuel pressure regulator) I finely got around to finding out the issue was the fuel pump. I replaced the fuel pump, cleaned the tank out, replaced the filter then cleaned out all the fuel lines with an air hose prior to reinstalling a new filter, pump sock, new fuel pump, and the gas tank. Car started and ran great. Here's the new issue:
While driving down the road car runs great, after a few minutes of driving the car will start bucking and stall right after I push the gas pedal down to accelerate. It doesn't happen every time, just when I push the pedal down as if to accelerate quicker.
Initially, I thought it was an ignition issue, so I started replacing even more parts (ignition coil, wires, rotor button, hall effect sensor, distributer cap) with no luck getting rid of the issue. I took the car to a "mechanic" to see if he could pin point the issue. He said it was for sure an Ignition issue and had me replace the ignition control computer. No luck, same issue. It did, however, make the car run almost like new as long as it is at idle.
I have also taken apart and rebuilt the entire throttle body to make sure there wasn't a clogged fuel line, or vacuum line somewhere. This also improved the idle dramatically.
I am now at the road block listed above and cannot figure out what is causing this thing to stall under load. I am thinking it may be the Cadillac converter? Anyone had experience with this symptom and a bad Cadillac converter? Any other suggestions would also be appreciated. I am really stumped on this one and need some outside ideas.
Thanks everyone for your help!
