"Little Black" started to misbehave. when i backed out of the driveway, she died, it was early so i just assumed i let the clutch go too fast. i tried to restart the car and nothing happened mad.gif . Here is what i found after some extensive spark plug pulling. The plugs were shot and corroded. so i replaced them. the car started fine after the new plugs were in. but when i accelerate the car started to stall out between 1000 and 2200 rpm. foot to the floor and nothing!!! i could get up to the higher rpm range and she did just fine. there sounded like a misfire at idle. At this point i decided it was time to change the fuel filter with my thoughts being that there was a fuel delivery problem. the filter was dirty and needed to be replaced but was not the problem. I thought maybe an injector cleaning was in order, that's when i was sure that i found the problem. the entire intake was caked in carbon soot, I've seen chimneys with less soot. everything from the back of the throttle blade to the intake gasket was a thick film of black, 2 days and 1 gallon of mineral spirits later the intake was clean and all of the carbon removed. surely this was part of the problem seing that 2 of the vacuum ports in the TB were blocked. NOPE!!!! mad.gif After reassembling the freshly refurbed intake and TB the car started and reved great, i removed the car from the lift and took it for a drive, great throttle response, perfect, for about 14 minutes and then the sputter and stalling started again. I could use some opinions here.

thanks for the reply.
I think i know what you mean by jumping the terminal. how will this tell me what is wrong though?
over the past week i have narrowed down what it it not
New spark plugs.
New fuel filter.
Fuel pump works just fine.
Entire intake was removed, cleaned and checked for leaks
Throttle body was cleaned

I tood the distributor cap off today and saw that the rotor was badly pitted and slighly corroded. i cleaned the rotor and the 4 points to remove corrosion.

It seems to stall more when the car is up to temp, and it only stalls coming off idle, once i reach 1500 it will rev with great response.
What would cause a car to loose the ability to rev at low rpm but not at high rpm?
