keish Posted January 6, 2011 Share Posted January 6, 2011 Howdy....... New(est) problem with me 94 Loyale. Need some diagnosis help.... Background; 94 Loyale, 234k miles, just replaced axles, ball joints, calipers/pads.... Driving to NY from Alabama, subbie starts to give a stutter/heave/lurch from the engine when going over 3k RPM in 5th gear generally uphill. I could go 75 on a flat or downhill but on almost any incline I could hardly keep at 60 before the heave would happen. You could feel it start to stutter a bit before it would make its big lurch and if you really babied the gas pedal you could drive fine (slowly) and not make it happen. I'm home now, searching threads trying to find out what my problem may be. Help me out... At first I thought it felt like my clutch was slipping, it sort of feels like when some when else is driving my car and they ************ up shifting into 1st, that sort of lurch forward and shake, but my previous experience with clutches going is that ususally when you give it gas the RPMs rise but no engine doesn't respond. That's not what is happening here..... Could it be loose motor mounts? How could I tell if it was? The plugs are newish but the wires aren't, I'm going to replace those and see what happens after that.... Let me know what you guys think....

Numbchux Posted January 6, 2011 Share Posted January 6, 2011 Doesn't sound like a mechanical thing. More like a misfire under load. Could be caused by a lot of things, but an ignition problem would be most likely. start by checking the ignition timing. Then inspect and replace as necessary: plugs, wires, cap, and rotor.

naru Posted January 6, 2011 Share Posted January 6, 2011 Classic fuel starvation symptoms. Change the filter. Link to comment Share on other sites More sharing options...
keish Posted January 7, 2011 Author Share Posted January 7, 2011 Fuel filter will be changed this weekend along with new plugs and wires. Hopefully that's it.... What would cause the timing to need to be adjusted? Belt got replaced under 20k ago along with pulleys...... Link to comment Share on other sites More sharing options...
HATCHY Posted January 7, 2011 Share Posted January 7, 2011 I have kind of the same issue. My ride jerks, and pulls, when Im under load in low rpms. If I step on it it will straighten right up. letting off the gas will cause it to jerk. It sucks, I probably just need a tune up, or carb adjust Link to comment Share on other sites More sharing options...
