Question about 2003 Mitsubishi Montero

1 Answer

Engine shudders at 35-40.

While accellerating, the engine shudders between 35 and 40 mph. It doesn't feel like its between or changing gears, and doesn't happen while decellerating. Kind of feels like when you're on the highway and you go over those don't-fall-asleep bumps on the side of the road. Any help would be greatly appreciated.

Hi,

Appreciate the direct "Ask Me".

Initially
, what comes to mind is probable faulty universal joints (U-joint), actually two of them and/or missing retainer clips. They would be coupling the transmission to the propeller shaft and then to the differential. The power train is nearly perfectly balance system and any missing needle bearing on any of the four ends of the U-joint wold cause a slight wobble on a particular speed. To check, the vehicle must be lifted and the propeller shaft yanked. There must be no noticeable play or slack.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Why does my truck shudder when shifting into a higher gear with manual transmission 83 F100 Straight Six


not knowing the quality of workmanship used in the engine rebuild, it is difficult to answer exactly what is wrong
plugs and leads will not be faulty
I think the clue is in the remark about the carby being replaced and it ran a bit better
that indicates ,along with the very rich settings, that it could be an valve timing problem
I suspect that the cam shaft lobes are damaged or the timing chain gear is loose on the cam shaft
running well in the beginning and then slowly failing all points to the cam shaft lobes, cam followers or loose cam gear

Well, you did a really good job of describing the symptoms, but you didn't do so well describing the car. Are we talking about an automatic or standard transmission? are we talking about a four or six cylinder engine? You are asking about a drivetrain problem without giving any information about what drivetrain the vehicle is equipped with.

With all that said, IF we are talking about an automatic transmission being pushed by a V-6 engine, then there is a Technical Service Bulletin (TSB) that matches the symptoms you are describing. In this case, the problem is most likely being caused by a deformed or damaged exhaust pipe "A" mounting bracket.

Inspect the rubber bracket for cracks or torn rubber. If the bracket is damaged replace the bracket. Bend the stud on the exhaust pipe if necessary to get the stud to go through the bracket as straight as possible so the stud does not "ground" against the sides of the bracket. (see diagram)

My car is running a little rough when warmed up and I'm creeping along accellerating from 0 mph to 10 mph (like in a parking lot). By "rough" what I mean is there is a slight feeling of vibration I can...


mcdevito75 here, It is possible something in the tranny could be wrong especially if your tranny has a sensor that is read by your cars, computer system, a bad engine mount would cause the engine to shift position on the chassis while driveing, even just at idle. I would have your repair shop to look for a problem in the ignition system of the engine, coils, spark plugs, wires, also look for a crack in the cylinder head gasket, or a bad intake / exhaust valve.

Mine had a *bad*, but intermitent engine shudder (like it was running out of gas) between 30 and 40 mph. After 3 trips to the dealer, it finally did it in front of them. It's quite dramatic, so they admitted that I wasn't just bringing it in for fun and started guessing what was wrong. They found a TSB that recommended starting with one of the O2 sensors, which fixed it perfectly, immediately.

Sounds like yours isn't your engine - but I thought I should say something just in case.

1988 cutlass ciera boggs down when i accelerate


Hello! You have symptoms that point to incorrect fuel pressure.
First have the fuel pressure tested as follows; #1...engine running at idle: 13- 20 psi. #2...key on engine off: 23-30 psi. If pressure is incorrect change the fuel pump.

Does the engine "surge" at idle? If so, check the "fuel injection pressure regulator idle air control valve". Apply a vacuum to it; If fuel flows it is not the problem.
