An AC compressor puts a big strain on an engine when it's engaged. This is especially the case with low horse power 4-cylinder engines. What makes matters worse are high mileage engines which are in poor running condition. I experienced this with a Saab I used to have. I could only run the AC when I was moving at highway speeds. Otherwise it was too much ...

This hardly sounds like a problem for which the whole vehicle needs replacement. The symptoms could be explained by a misfiring cylinder, in which the vibrations are most obvious at idle and with the drivetrain engaged. Common causes for misfires include ageing spark plugs/wires, absence of spark or improper fuel delivery (usually a clogged fuel injector). ...

I have a 1997 626 Mazda 2L (manual) and it shook at idle and got progressively worse. It turned out to be the intake manifold seal. Its cheap to fix about $12 for a new gasket. To diagnose it is simple too, spray where the intake manifold joins the engine with a can of "jump start" or similar and if the idle picks up you have an air leak. Mazda's are prone ...

I had similar problem with my car too. During the 60 000 km check my mehcanic said they had to replace the "AC belt tensioner" because it was in bad condition. It didn't cost too much, worth a try. That 'click' sound after switching on the AC means that the AC clutch engaged and yes, it could be a bit noisy and it cause a strain for low powered cars. It's ...

So eventually car started idling really bad and CEL light came up with P0505 - Idle Air Control Malfunction. Did some diagnostics myself and took it to the shop. Conclusion was that IAC needs replacement. So I got it done and the adviser said that previous stalling problem was also caused by this. So far so good. I will accept my own answer once I confirm ...

It is difficult to pinpoint the exact reason for your idling issues without further information or knowledge of your Mercury Sable. However, a common cause for idling/stalling is a perished/broken/cracked/disconnected vacuum line that results in a vacuum leak. Vacuum lines are essential in maintaining engine idle. The fix would involve identifying any ...

I fixed the vibration problem I had for 1 year on my 2007 toyota camry after I cleaned the throttle body and air control valve (iac) the car is driving perfect. I can not believe it was so easy to fix...

These motors were plagued by problematic cylinder heads. Usually the end result in cases like yours are replacement of the Cylinder Head. Most likely there is either a blown head gasket or burnt exhaust valve. If there are no vacuum leaks and MAF is good then you need you start looking deeper into the engine.

It could be caused by ignition cables, coils, plugs, I have had the same problem in my Skoda Octavia ยด00, in the morning it was like one of cylinders is not having a spark, combustion was very bad and power was reduces but only for max 5 minutes, then after engine got heated a bit it disapeared, also this problem is related to damaged gasket under the ...

Replace fuses that go to computer shutdown, #11 &14 I think. Or re-seat all fuses in the fuse box under the hood. The spades on the fuses build up a thin corrosion that gives a voltage drop.[they got me for $1200] new computer and new plugs in my 2006 300c
