I'm having a problem with my 2005 Artic cat 400


things that could be wrong.
compression leak (Piston rings or valves )
fuel (fuel air mix)
ignition (spark plug lead or dispack)
battery or alternator power
spark would be my first though as this needs to be working properly for full range. weak spark will run but will over tax the engine at speeds. if the engine is running fine until a certain speed then this would be affected in affected flood the spark. can als be the alternator if the battery is not charging correctly.

Toyota Rav 4 1997 .Check engine comes on .Codes are P0301,302,303,304116 . What to do.


The engine coolant temperature is high. Your other Codes are for missing cylinders on cylinder 1,2,3,and 4. Get the Codes cleared and start over. Changing the plugs and wires,etc could have generated the missing cylinder Codes.

Autozone,Advance, and Oreilys will scan for free.

Check your engine for an IDLE SPEED CONTROL SOLENOID, which may be in the intake. Or a fuel pressure regulator.

A lot of times people work on the spark side and forget the fuel injectors. They can cause a miss.

I have a 1998 Honda Accord 6 with approx 100K miles. Recently it started a mild stumbling at a steady 38 mph. Not sure how else to describe it. It doesn't appear to be missing. If I change to a...


Often as an engine ages and parts wear out rhythmic oscillations can cause a obvious and repeatable noise. Even when new, hitting a resonant frequency (for my personal car holding at 1500-1600rpm causes a terrible noise and vibration) If you're only experiencing sound as a result of the speed it is probably not a major mechanical issue. However, I have had a car before, about the same year as this one, where as it tried to shift gears at about 40mph into fifth gear the engine would bog down, detect low engine speed at prepare to downshift, and would repeat this process. Solution to that was cleaning the fuel injectors (which will run you about 50$ most places.)

Thermostat location1998 bettle


VW Bugs use a tiny accordion looking thermostat that is attached to shutters on the fan shroud. When cold the thermostat pulls the shutters closed to impede the flow of cooling air. When hot the thermostat expands and pushes the shutters open to allow airflow over the engines cooling fins. Changing it is a piece of cake and in fact much easier than the original answer. It's done from the bottom of the engine. It's the only accordian looking thing under the car. You will need to remove a piece of cooling tin on the bottom of the motor to get access to it so in addition to a flashlight and screwdriver bring a 10mm wrench. (Now would also be a good time to get a couple cans of brake clean and use them to clean off the oil and dirt on the bottom of the engine and cooling fins). If you have further questions or need more instruction I strongly reccomend you get a used Muir Manual from Amazon and thumb through the section on cooling. In my opinion VW Bugs should have been equiped from the factory with the Muir Manual.

1967 PONTIAC 400 cu.in. ENGINE-What is the right number head for that year engine,also can I put a 1975 crank in a 67 engine block without machine work. THANKS FRANK


Pretty skimpy info there toolbox. Which engine do you have?
In 1967 Pontiac made 326, 400, and 421 engines. They all have the same main bearing size, 3.00 inches, rod size, 2.250 inches and the same stroke, 3.750 inches.
In 75, they only made the 400 and 455. The 75 400 uses the same crank but the 455 uses the same rod size but a larger 3.250 main, and 4.210 stroke.
So any year 400 crank will fit any other year 400, 389, or 350.
Google Kauffman Racing, Wallace Racing or Pontiac Dude.

Cheers
