1995 Mercury Grand Marquis Q&A
1995 Mercury Grand Marquis Question: Why won't my engine not rev past idle?
Was going 60mph, suddenly engine lost all power. Would still drive, but not beyond idle. Even in park, tried revving engine but it seemed like it was bogging down and never revved up. Had to pull it up hill at end of drive to get it in garage as it lost momentum and could not make hill. No advance warning. Only other problem that may or may not have any bearing, is the starter has been intermittent. Not clicking. Some times it starts just fine, next time may have to try several times then suddenly it turns over, or it doesn't at all. - lwcamboy
I would first check for codes then I would check the fuel pressure and the fuel filter it they are ok I would check your cat converter to see if it is plugged - goodguy
