I'm having a issue with my 87 T/A hope someone can give me some insight. Recently after the car warmed up I do some miles in the city I'd have a problem on take off. It'd be a quick bog and cleared up immediately. Only did this when it was at operating temp and after a drive. Well today and yesterday I've notice some bad bogging during acceleration through the whole curve. Today the engine dieseled for about 15 seconds after shut off. It's never done this before.

It's recently had spark plugs, wires, new distributor, coil. What would make a TPI diesel like that? I've searched and only read about it doing that with carburetors. Any help would be greatly appreciated as this is my daily driver.

 

Well I seemed to have fixed my bogging and dieseling issue. It was the base timing. Also adjusted my TPS from .71 to .54 which seems to be the noted measurement. Now I have a issue that I've had for some time now. A miss that is very noticeable at idle. I've replaced everything ignition wise and it still does it. Only time it won't do it is when I unplug the EST. What could that be?
