[PATA]

Last fall My '89 K2500 suddenly came down with some engine malady. Snow and cold came so quickly that I could only work on it intermittently through the winter. Now, I have followed up on what I performed late fall and still the engine is not running well at all. I think I may have a bad cylinder... Help.

At first last fall I smelled an electrical burn. Truck would not run at all. Kept popping the computer fuse. I pulled the module (brain) and sure enough it was totally cooked. Replaced it and managed to get it to run. Then lots of snow and I left it till this past week.

Started yesterday... no power at all. Feels like it is not running on all the cylinders. Basic tune up was performed last fall (Cap, Rotor, Wires, Plugs). I am also getting an error code... O2 sensor. Have not replaced that though.

What should I do... compression check? Engine is a 5.7 350 TBI. What should the compression be in each cylinder... AT least ?

Any other suggesitons? Last thing I need is to replace the engine!... I fear that is where I am headed.

Thanks!
