Why does a 1993 Plymouth Colt 4 cylinder engine idle rough when the air conditioner is on?
Hey Bill== An a/c takes about 20 horseower to turn the compressor and a 4 cylinder is developing about 30 horsepower idleing so it will slow down and be rough. Sometimes there is a solonoid to help compensate for this but it doesn't help a lot. GoodluckJoe Check your idle air control valve for lack of movement. When you turn on your A/C it puts a load on your engine, the IAC valve compensates for this by increasing the idle. If it's bad or is not being controlled correctly that rough idle you described will occure due to the load on the engine. Regards, Kevin
A spark plug is used to ignite the fuel/air mixture inside the cylinder of an internal combustion engine. If the spark plug isn't working, the cylinder won't fire. In a multi-cylinder engine, this will result in rough running and loss of power. In a small, single cylinder engine, this will result in the inability to start the engine.
A new engine would have 150 LBS or more per cylinder. A used engine that runs real good and that has plenty of power should have at least 140 LBS. per cylinder. If there is more then a 15 LB. difference in any cylinder then you will have a rough idle and maybe an engine miss at a idle. That means there is an internal engine problem.
My 1965 mustang 6 cylinder 200 engine starts running rough and the motor shakes at a stop and stalls out and then its hard to start and blows out white smoke when it does start?
rough idling Try cleaning the throttle body with throttle cleaner and tooth brush. Remove the cover first. Soot builds up in this area causing the flap to stick resulting in rough idle. I have cleaned mine to new condition and I still have a rough idle. The dealer told me these motors never idled very smooth in gear.
What would be wrong with a Chevy s10 after changing timing chain the timing is right on but runs rough no compression in cylinder 4?
It should have 150 PSI per cylinder. If it has a reading of 90 LBS. are less on any given cylinder, Then the engine will idle rough at an idle. / engine miss. You can't have anymore then 15 LBS. difference in any one cylinder. 150 LBS per cylinder is a good reading on a fresh are good running engine that's in good shape. You may have only 120,130,140 or 150 LBS. That is your…
92 Plymouth Acclaim 4-cylinder won't shift into overdrive 300rpm at 100kph runs and runs rough at idle what would cause this?
1992 Ford Thunderbird SC After starting the car this morning it ran rough and all of the sudden it poured white smoke?
Mine is 2000 Daewoo Leganza with 100000 miles It takes too much coolant you put 5 gal of coolant and you hardly drove 200 miles And it is throwing white smoke The engine idling is very rough?
you either have a cracked cylinder head that is leaking coolent into the combustion chamber causeing rough idleing and eventualy total engine failure. to check this pull out the oil dipstick and see if the oil is thin or watered down you either have a cracked cylinder head that is leaking coolent into the combustion chamber causeing rough idleing and eventualy total engine failure. to check this pull out the oil dipstick and see if…
Can you help you your 2004 Chevy 4 cylinder after 3 trips to the shop for check engine light and running rough now you have white smoke from tailpipe and again running rough but no light whats going?
Many rough idle problems are the result of burned valves. At a higher speed, the engine may not seem to be running rough, but may still be misfiring. On the other hand, if a valve is only slightly burned the cylinder may actually fire. It can also be a bad sparkplug, wire or distributor cap. In any case, you'll need to find out which cylinder is misfiring. If you've encountered a misfire problem that seems…
2001 spectra check engine flashing running rough computer says cylinder 3 misfire replace plugs runs great for 5-7 miles then check engine flashes again and starts running rough again whats up?
I'm not sure maybe there's a fan somewhere...maybe you stopped using conditioner. If you have rough, static hair, then use conditioner. I prefer Aussie conditioner but it's up to you. Conditioner gives you smooth, flat hair that's soft. Aussie conditioner comes in purple bottles. Aussie gives you soft hair after only one use! Good luck!
Spark plugs are used to ignite the air / fuel mixture in the engine The ( 8 ) spark plugs ( in your navigator ) are needed for the engine to run properly For example : if the engine cranks but does not start the engine is either not getting fuel , SPARK , or air Another example is if an engine cylinder is " missing " so the engine is running rough the cause…
1999 Dodge Grand Caravan 3 point 3L is sputtering backfiring and rough idling but no check engine light is on Any suggestions as repair shops cannot figure out problem?
Losing any of your plug wires will make it run very badly, on a 8 cylinder it may not kill the engine, but it will run rough, 6 cylinders and 4 cylinders have fewer cylinders and may shut down if 1 is lost, but i've see them keep on chugging away, just very rough sounding. You need to get it replaced as soon as possible, driving like that will damage the engine.
1994 Plymouth voyager 6-cylinder was idling rough for 4 months and mechanic said it was just a dirty injector but now it stalled after making a turn and wont start?
You washed your engine at the car wash with engine cleaner with the engine running every since then your check engine light has been on and sometimes blink steadily There is rough ideling to.?
There is alot more that we need to know to answer that question better. Year of the engine is 1 thing we must know. The odds of a intake gasket letting oil into a cylinder is slim to none. The most common cause of that would be BAD valve guides and valve seals. You may also have bad piston rings are a burnt piston too. One question that we need to know is, Does the…
