FYI...
Well... an update, after a few more trips to the mechanic (after getting some engine error codes from "non-prophet" - THANKS!).
Wednesday the mechanic told me cylinder no. 4 has low compression, about 70 psi vs. the 150 psi of the other cylinders. Mech. stated he is not going to charge me anything till the problem is fixed. He is still guessing could be about $100-200. Will need to rip apart the engine to check the valve, piston, rings, etc. Hopefully, this will get fixed soon... says he can get to car in May, a little over a month... At least, I can drive the car...
Thanks for reading and as STaL (Mark) says, thanks for the concern/sympathy...
