A couple of months ago my 93 EB 2dr auto (186K) started to stumble when coming off idle. Fixed this same problem 2 years ago by cleaning MAF and throttle butterfly. Before I got around to cleaning both again, the engine began to shake at idle (tach steady at 750) and really shake at part throttle. Smooths out above 2000rpm, but there is a power loss. At 55 (1800) in 4th there is boom like lugging in a 65 VW. It does not stall and gets 16 mpg. Could not find any vac leaks, cleaned MAF and throttle several times, added gas anti-freeze and fuel inj cleaner, replaced plugs (looked good) and wires. Unplugged MAF and it ran worse. Pulled plug wires at EDIS with good spark. Ran codes using EEC and CEL several times, KOEO - 111, CM - 157; KOER - 111. I have not cleared codes ie. CM 157. Can anyone help?
