SOURCE: car running sluggish and rough. multiple misfire.

Hi there, sounds like this car might have either a bad coil pack or the distributor cap has gone bad. 3 most important things are air, fuel and 12v power. Seems your getting all three but one of them is giving you trouble. Sounds like spark. Try a new distributor cap or a new set of coils and see if that solves the problem.

if it isnt the spark it has to be fuel or air which would lead to lack of fuel pressure which can cause sluggish behavior or the air sensor in the intake if there is any is not working properly and the computer is running on a safety fuel map that is a base map used by manufacturers which burns alot of fuel but stops the engine from destroying it self. Check the coils o the sensors.

SOURCE: I have a 1997 Mitsubishi Galant with rough idle

I am having the same issue on Mitsubishi Galant 02. Clattering on acceleration, herky jerky idle. Pulled a code multiple cylinder misfire. My mechanic's diagnosis is bad valve cover gasket causing oil to seap into the spark plugs and bad timing belt, which I have not replaced at 150k miles. I do however know my fuel injectors do need cleaning, he hasn't ruled that out either. Have you pulled any code on it? I have read on engine knock sensor going out on some of these also. Hope this helps some.

I have a 1987 ford ranger the engine turns over but it wont start

Would the timing keep a 1996 ford thunderbird from starting


Your car only needs three things to run:

Fuel
Air
Spark

If you have checked the air filter, fuel filter, plugs, leads, and coil(s), then you are either looking at a mechanical fault, or electrical fault.
You haven't mentioned yet if the car has spark, only that you replaced the leads and the plugs. Try pulling a plug out, plugging it into a lead, grounding it and cranking the engine. Do you have spark?
If not, then check and replace the coil(s) and try again.
Also check the condition of the air filter.

How old are the spark plugs and wires. GM vehicles are great runners until something goes wrong with the typical spark or fuel delivery issues. Wires or fouled plugs may not set off the computer, it will just run crappy.

Could only be a few things. The coil #1, Fuel injector #1, Stuck intake or exhaust valve, or blown head gasket allowing coolant into cylinder #1. Use a spark tester to check the spark coming out of cylindr #1 if checks good then ohm test the injector when it is warm. Check other injectors to compare. Do a compression test on cylinder #1 and test other cylinders to compare. If cylinder is low compression suspect valves and or head gasket. If compression is low then het a leak down tester to test if a valve is broke or sticking. On your sable i would suspect injector or coil most likely.

Cylinder number 3 misfire


It can be a bad spark plug, plug wire, burnt valve, blown head gasket, or worn piston rings. Replace the spark plugs and plug wires and see if the miss goes away. If it does not then have a compression test run on the engine. In addition if you are loosing coolant with no apparent leak, and you see white smoke coming from the exhaust you may have a blown head gasket which will cause a miss.

99 5.2 durango :pulled codes for multipe missfire cylinder #5-7


Aloha We have just replaced all of what you have replaced, plus water pump, fuel pump, pcv valve and 02 sensor. Took it to mechanic today we had misfire on 1,2,6,7. Mechanic said that the 99 dodge is known for bad computers, he checked ours and works great turns out that it was the coil. Ours was jumping 1/4 inch and had a orange/yellow spark. it is supposed to have a 1 inch spark and be blue. This has solved our problems after 527 dollars later.
Check the coil!
