Having problems with your 2003 Dodge Intrepid ?

Went on trip, drove a little over 500 miles to destination. When went from one freeway to another car seemed to go into a limp mode after slowing to bout 20- 25 mph. I reset by putting it in park turning car off and restarting. After getting back home it started doing this more & more. It seems the car goes into limp mode after reaching speeds of 40-50 miles per hour and then slowing to about 20- 25 mph. I have the codes; P0456 Evaporative Emission System Leak Detected (very small leak) & P0440

2006 Saab 93 SportCombi 2.0 t with 32k miles. I just bought it 2 months ago. The check engine light comes on everyday! I'm in sales so I am driving it most of the day. It puts the car into limp mode EVERYDAY!! After it sits with the keys out, most of the time it comes out of limp mode. I took it to a Saab garage (not a dealer) that has worked on saabs for 25 years.

Electronic throttle control symbol illuminated this morning and the engine went to a limp-home, what does it mean, and is it costly? Driving to the train station in Atlanta this morning the symbol came on and the car slowed down. And I turned the car off and sat for a minute with the caution light on. Then turned the car back on, made it to the train station, and didn't have a problem. Should I attempt a 400 mile trip on Sunday?


I would not recommend any trip until the car is repaired. The symbol in the dash means the car was in limp mode. It could be caused by the T/P sensor, this is the most likelt problem. ... 2004 Lincoln LS

The engine icon warning light has come on in my 2005 S-type 4.2 jag (50,000 miles). According to the manual, this means that something is likely wrong with the electronic control system for the engine. It happened once before, and the car went into limp home mode, but it has not done that this time. I have my car into a jag dealer, and he says the diagnostic for the engine controls has not revealed the source of the problem, but it does indicate many "faults". His solution is to begin trying

2002 Chrysler 300m, DTC codes P0700 and 1776. Had an issue 3 years ago when car was bought but it was just the 1776 code, had it looked at and found it to be the soleniod pack, i replaced it (trans build date is concurrent with the TSB stating "Not" to replace valve body, just soleniod packs)and have never had an issue in 50,000 miles until today when the light came on and it went into limp mode. Just unsure having the 2 codes this time. I have kept up on servicing sice repair.

I own a Chevy Malibu 2003 LS, fully loaded and 54,000 miles. I was driving approximately 20 mph in a 45 mph zone. There was a car in front of me going extremely slow so I sped up to approximately 40 mph to pass. My car continued to speed up. I hit the brakes and immediately after taking my foot off the brake pedal the car sped up as if the gas pedal was floored. I hit the brake pedal and shifted into neutral after going almost 80 mph.

My '99 Land Cruiser has gone into limp mode twice in the past several months. First time was when I was restarting it after a short break. We pulled a battery cable, and the "Check engine" light was cleared and it ran fine. Recently, it was after running it for about a mile - the "Check engine" light came on and it went into limp mode. After letting it set for a few days during the holidays, I went back out to see what I could do, and when restarted, the check engine light was gone, and vehic

Hi - I have a 2002 jeep liberty. I was driving down the highway going 70 miles per hour and it went into limp mode. Stopped and disconnected battery to reset codes. Started driving again and it made the 1-2 shift. On the 2-3 shift it drug the shift and went back into limp mode. I believe it may have broke the screws on the accumulator cover and let the 2-3 accumulator dislodge out of the bore. Is this possible or what are your thoughts?

Go out in AM, car is cold, starts and runs fine. Drive short distance, stop and restart, runs fine, idles fine. Drive about 8 miles at 50-55 mph, pull up at a red light, when speed gets down to ~25-30 mph, car stalls. Carburetor has been rebuilt. Put car in neutral or park right after it stalls - it starts right up and will run until you slow down to 30 mph or slower, stalls, As long as choke is closed enough, it seems to run fine.

He said he was going about 30 mph when it just went out as if it was thrown into nuetral and he just coasted into a parking lot.

Hi, I have a 1994 Eagle Summit Wagon, AWD, 2.4l 4cyl engine with automatic transmission with overdrive. 105k miles. It is made by Mitsubishi. The car has been working perfectly until yesterday. I started the car and drove about 2 miles at 60 mph and suddenly the tranny went out of gear. All forward gears and reverse were equal to neutral. I coasted to an uneventful stop. No unusual sounds or events prior to this. I added a little fluid but not much was needed. I turned off the car

I have a 2006 kawasaki prairie 700. The belt light was on and it was in limp mode. It would only go about 15 mph. And the 4wd was out. I replaced spark plugs, belt, choke cable, 2wd/ 4wd actuator, and had the carbs worked on at a shop(also tried switching grey and black plugs to reset light). None of this worked. So i bought a dynatek cdi box and switched it with the old one. This fixed the problem and the belt light went off. I rode it for a half a day and now its back in limp mode like it was.

After about 100 miles, the check guages light came on and the volt(battery level) guage went to zero like it shut off. I stopped and shut off the car and restarted it and the volt meter started working again, but only reading about 12 volts instead of 14 or so where it usually is. We kept going and every time i shut the car off and restarted it, the guage would shut off at about 30 or 40 mph. The batte
