Question about Cars & Trucks

Open Question

I have a 2005 mercury mountaineer which was having battery problems. I was getting a jump after first trying to remove the battery. It finally started after about a half n hr but after it started it went into engine safe mode and limp mode. I then shut it off and took the battery to an auto store and got it checked and said my battery was bad. I replaced the battery but it will not come out of these modes??? Any suggestions?

SOURCE: 2005 Nissan pathfinder slow acel. Limp mode? HELP PLEASE

it does seem that that might be the problem. the only way that you can fix it is to go through the ecm and reset it. this requires a diagnostic scan tool not just a code reader. when the tcm was changed was the ecm cleared?. if not this would explain alot because the ecm still thinks there is a fault. please rate this thanks.

SOURCE: possible bad alternator?

I went through three alternators before we found a good one for our saturn sl2. Now she has been good for two years. All I did was go back to where we bought it from, they hooked up the alternator to a machine and gave us a new one when it read that it was faulty.

SOURCE: transmission going into limp mode.

Change your input/and output speed sensors, check your fluid level in the tranny, test cam sensor. If problem still occurs then check the tranny solenoid pack and replace as needed. It is important to understand that in MOST cases, the plug in connectors to these sensors are worn and the plastic part of the plugs expand when the engine warms up and then the proper connections are lost. MOST of the time a sensor works fine but either the wire OR the connector itself is not working. Always check these connections first as most of the time this is EXACTLY what your problem may be and your repair is free!

2005 Mountaineer 2 wheel drive, 6 cyl hard to shift when parked on incline or decline and doesnt feel like shifting into overdrive. Sometimes jump a few inches when put into reverse. Any thoughts.

Yes when you park on an incline you should always put your emergency brake on before shifting to park. Then whenyou are ready to move again put you car in gear before disengaging the emergency brake. this will remove the stress from the transmission.

Car will not start. Battery sounds like its geting enough jump, but will not turn over.

first of all if its an automatic, put it in neutral to try to start it. if it starts its the neutral safty switch. I had a similar problem awhile ago with a friends car,- disconnected, cleaned and reconnected both + and - cables at the battery and starter/grounds. The main cable connection to the starter was so corroded, I'm surprised it ever started. No problems since a good cleaning and tightly reconnected.
