Alright guys I need a little extra wisdom for the problem I am having. My car ('73 2.0L FI) has hesitation on acceleration. Sometimes you can barely notice it and sometimes it completely refuses to gain speed and other times it just feels sluggish. It doesn't necessarily run rough, just hesitant an sluggish. One day I might drive it without any issues and the next it starts acting up again. It is not heat related because it will act this way with the engine cold or hot.
-I have tried changing out trigger contacts, I also cleaned up the distributor -Ground wire in Distributor is still connected -I replaced the CHT -I have changed out the TPS with no success -Dwell and timing is on spec -I adjusted the valves -Distributor cap and rotor were replaced -I played around with the spark plug wires and it doesn't seem to make a difference. -Fuel pressure is good at 28 psi -Fuel sock in tank was replaced 2-3000 miles ago and filter was changed not too long before that -Coil and condenser replaced I have probably done some other things but can't remember it right now. Another note that I should probably include is that when the car is acting its worse, when it doesn't want to accelerate at all, I sometimes get the slightest backfire out of the exhaust. Would this more than likely point to the ignition system? I guess the next things to do on my list would be -Replace the spark plug wires -Replace the points, although they look fine -Change out fuel Filter Anything else I should look into? Anyone have any thoughts on the next steps I should take? I appreciate any and all help! Oh and a picture for shits and giggles! |

I agree about dwell, double check that. Do you think there might be a pinched fuel line under tank that getting pinched while driving? Maybe a bad electrical connection for fuel pump, that is intermitant? Best of luck.
