i have a 95.5 isuzu rodeo, it has 135000 mile on it. i bought it new and has ran good all that time. just the other day the motor started shaking when i was at a stop sign. and as i drove it the whole car would shake. i got home and changed the spark plugs and tested each spark plug to make sure i was getting fire. i was. but it is still doing it. what do you think is the problem?

Have you checked for vacuum leaks? Have you checked fuel pump pressure? Has the check engine light come on?

no the check engine light has not came on. i have looked for vacuum leaks but have not found any. I have not checked fuel pump pressure. The car has a rough idle when in park and the car shakes or vibrates at about 40 mph.

I have looked for leaks in the vacuum lines but cant find any. There is no check engine light on. I have not checked the fuel pump pressure. The car vibrates around 35 mph and the whole car shakes and does it in park or at a stop.

Check the pump pressure and let me know what you find. Also, when was the last tune up?
