Check that all the plug leads have been fitted properly as it sounds like a wire has fallen off a plug.

I had this problem too exept I have no clue what parts or blah b;ah blah. I just know that my coil pack was getting fried.burnt out because my wires were bad. The mechanic I went to was a moron because I took the car to him 3 times and he kept saying it was the coil ad kept replacing it. I took it to my uncle and he said my wires were in horrible shape and when this is the problem it fries your coil making your car run like a lawn mower! Well all i did was replace my wires and the car ran great! Well I hope this helped..

SOURCE: eng. shakes spits/sputters oil in spark plugs

I just had this fixed on my suby today. The cause is that the spark plugs, go through the valve covers on the 2.5 l .When the o rings in the cover go, the result is oil in the spark plugs. The cost of the repair in Canada was about $500 including diagnostics as well as new plugs and wires About 1.5 hours labor and new seals and gaskets. It now runs like new. This is a common problem for this subaru engine as well as for the dodge neon.

SOURCE: 2000 ford super duty 7.3 diesel will not cold start

you need to have the engine coolant switch checked,since the computer relies solely on sensors,the ect tells the computer how cold or hot it is so the computer will make it a rich or lean mixture to start the engine,if it tells the computer that it is 75 degrees the computer will lean the mixture like starting a car in the winter without a choke.

SOURCE: 98 S10 2.2, code said

40 psi fuel pressure on 1998 chevy S10 is very less.------ It should be approx 50 to 55 psi.------ Try starting with starter fluid and see , if it is running rough or getting smooth with starter fluid sprayed on throttle body.-------- Dont drive too much, with starter fluid sprayed.Tjhis is just for testing purpose.If the truck runs smooth with starter fluid sprayed, then get the fuel pump and fuel filter replaced.The pressure of fuel pump is less.-------- But with starter fluid sprayed, you notice same running rough problem while test driving, then the MAP sensor is problem.------------ A faulty map sensor can cause the problem, what you mentioned.--------

The Manifold Absolute Pressure (MAP) sensor is a key sensor because it senses engine load. The sensor generates a signal that is proportional to the amount of vacuum in the intake manifold. The engine computer then uses this information to adjust ignition timing and fuel enrichment.

When the engine is working hard, intake vacuum drops as the throttle opens wide. The engine sucks in more air, which requires more fuel to keep the air/fuel ratio in balance. In fact, when the computer reads a heavy load signal from the MAP sensor, it usually makes the fuel mixture go slightly richer than normal so the engine can produce more power. At the same time, the computer will ****** (back off) ignition timing slightly to prevent detonation (spark knock) that can damage the engine and hurt performance.--------

A low intake vacuum reading or excessive backpressure in the exhaust system can trick the MAP sensor into indicating there is a load on the engine. This may result in a rich fuel condition.

----------
Replacing the sensor should help.--------

thanks.Helpmech.

My miata shakes at 40 mph


Although you didn't say if it feels like the shaking is coming from a wheel, it sounds to me like you have a bad tire even though they are new. Take it back to where you got the tires and have them take a look. If they can't see anything, ask them to take it for spin.

Find your EGR valve & try disconnecting the vacuum & or wires to it temporarily and see if it changes anything. Be sure if it has a vacuum line, you plug the line with something when you remove it.

Changing spark plug wires


WEll u dont need to remove anything This is what i did lift your car up with a jack. where you oil filter is you will see you plug wires running into your (ICM) Ignition Module unplug them and slide them to the top of your motor. dont get them mixed up otherwise your timeing will be messed up and your car wont start. on the ICM from the top to bottom the plug numbers are 2,3,1,4 and on top of the moter from left to right 1,2,3,4 just make for sure u have the right order..
