what could be doing this
replaced TPS , coils , cam & crank sensor. The car starts runs fine at first the more time you drive it the harder it gets for the engine to rotate . Like something is stopping the rotation .have been doing on vehicle repair since 1969 and don't no were to lookne
Boy, if you could give better description of what it is doing....fuel issue? Plugged catalytic converter? Torque converter locked up? Oil in the engine? Brakes locked up? You mean the engine wants to die?
Is the engine trying to seize up? I had something like this happen on an old GM 2.8. It would start just fine but as it ran the idle would get slower and slower till it died, you could crank up the idle and it would still do the same thing, you couldn't drive it cause once you took your foot off the gas it would die and would not crank, once it cooled off It was fine, start right back up, no noise or nothing, finall torn it apart and found a separation in the block that would expand as it got hot and would start putting sideways pressures on the cam and crankshaft as it was in the webbing, sounds wierd I know, wound up replacing the engine with a short block. Don't know if this is something similar or not, just one of my experiences.
