Just did full valve job, belts, pulleys, water pump, etc... Done many before so pretty good at it. No corners cut. Fel-Pro gasket sets, etc... The car runs smooth and idles great. Seems to rev fine in neutral or Park. From a dead stop if you nail it, it does not jump off the line and the transmission takes a few seconds to downshift into lower gear. ( I just changed most of the fluid and the spin on filter. carefully and slowly got the fluid level perfect.) If I start up a hill and gently apply throttle the engine has very little power (no misfire... just no go.) Plus transmission takes it's time downshifting. Once you get rolling or on the highway, it has no problem hauling rump roast. And the transmission runs right up to 6K redline and shifts right to the next gear. Also shifts manually to all the gears no problem. We hooked up a super nice Matco scanner tool today that reads everything while you drive, etc... No codes. Can't find any vacuum leaks. Changed the fuel filter and lines. Tried spark plug wires. Gas is fresh. Still will not go off the line or uphill! Please.... If anyone has any logical things to try, HELP ME! Thanks in advance!
Yesterday I had posted in the 'What have you done today thread.' All I had done was to replace the upper body complete with injector, throttle return spring & FPR without removing the lower throttle body from the intake manifold. Didn't have to disturb the coolant gasket nor the TPS this way. Problem was throttle response was feeling like the car was bogging similar to a too rich jetted carb. And the telltale smell of fuel out the tale pipe when engine was cold! Not good for the cat converter. Fuel injector was supposedly a 'rebuilt' unit in the SPFI body I had bought from a seller. The Air Control was new, but a used TPS & "rebuilt" injector. Had bought another throttle body complete on a PNP 50% off day almost year ago. Why not try it? Easy experiment. Timing set at 20*, TPS adjusted correctly, good plugs & wires, distributor checked out OK, fuel pressure OK. Etc. Here's some info from the 87 FSM for anyone who needs it.
