Go to Autozone and ask them to read the code. I am thinking O2 sensor because it does not idle well.

79 series turbo Landcruiser ute idles fine although the engine shudders at higher revs. No miss in the engine or popping in the exhaust. Shudders to a stall sometimes during takeoff. Engine and gearbo


start with a compression test to determine if there is a weak cylinder or imbalance . the stalling could be fuel related... check pressure and change the fuel filter. more info is needed...... lots of vacuum lines and emissions controls, are the all there? is there a vacuum leak somewhere like the intake, pcv, throttle body or plastic tee?

Decreased engine, now it shudders & idles rough


The water has gotten past the plug boot seal. Pull the plug tire off the plugs and use some compressed air to blow out and dry the plugs. Some times the water can really get deep so don't pull out the spark plugs.

2000 Land Cruiser flashing check engine light and the car is running rough/shuddering


The warning light is telling you the computer has found a problem that is affecting engine performance and fuel mileage. A flashing light means it is something serious.
You should have someone scan the computer for trouble codes and go from there. The codes will help direct the mechanic as to what to test.

Shuddering at idle in a 2002 mercury cougar


1st to second sounds like a forced shift i would check the 1-2 shift solenoid inside the transmission and make sure the speed sensors are all in good working order, clean and apply electro grease to plugs on the transmission , as for the idle problem it could be many things from sensors for the engine to a torque converter lockup solenoid need more info is the check engine light on? you said it shudders is it missing or has a surging idle ( high and low) does it die when it goes low idle or stay running

Idle is high at start - 1800 rpm. Seems like excessive white smoke from exhaust. Put into reverse and back out of driveway it has a regular shudder (bump bump bump) but not hard metal grinding sound.....


white smoke out of the exhaust would be a sign that it is burning coolant... if it goes away after it warms up, it could just be condensation inside the exhaust pipe. 1800 rpm is a very high idle, maybe have your IAC motor on the throttle body checked... check engine light? if so have the code read at your local auto zone.

Engine shudders when idling in gear, check engine light on


Take a run into Autozone, or Pep boys, or similar big autoparts store and they will do a free code scan, to point everyone in the right direction instead of guessing, and throwing parts at it. If the fix isn't obvious after codes recorded, get back to us with code(s) and will help you out if still needed.

I have a 93 ford probe se the fuel cutoff light is on


when you are traveling about 35 or 40 mph press the brake just hard enough to make shudder let off do it again let and off. if you can control the shudder that way then its the brake if does not do it til you slow to a certian speed then the problem may be engine related. As far as the low idle there is an idle stabilizer which can definitely cause that problem. Or in some case an aged timing belt can cause similar issuses
