This may be a sign of a vacuum leak. High idle speed, stalling and hissing sounds are common signs of a vacuum leak. When a vacuum leak is present in an engine, this causes an excessive imbalance in the air/fuel...
Alternators are tested using a voltmeter while the engine is running. If charging system output measured on the battery posts is around 14.2 to 14.8 volts (see your Service Manual for exact values), that represents normal alternator operation. During one...
Before replacing all the coils and plugs you may need to have the engine decarbonized. The engine can have excessive carbon build up on the exhaust valves, cylinder head, and exhaust manifold. You should use engine combustion chamber cleaner on...
Hi there. Anytime you complete repair or replace mechanical components, it is critical to remove the battery terminals before any further steps. It is possible that if the battery cables were not removed, that you've burned a fuse or relay....

It could be that the speed sensor is bad. The transmission will go into limp or safe mode when it loses one of its main inputs, such as the transmission speed or transmission range sensor. It may also go into...
Although your problem with the oil pressure warning is probably instrumentation. It's a bad idea to ignore oil pressure warnings. If the oil pressure is actually low, it will do serious engine damage very quickly. The thing to do is...
A flashing oil light is typically a sign that either the oil level is low, or the computer has sensed a lack of oil pressure. I hope it isn't the case, but usually when an engine starts to lose power...
First of all, overheating the engine will damage it. The list of reasons why is long, but here is a partial list of reasons why overheating the engine will ruin it. The engine oil becomes much thinner at...
