95 tacoma 2.7 liter cranks and idles fine once throttle is applied to take off she hickups and jerks and runs horrible.. Replaced the coil, rotor cap, plugs, and fuel filter.. I cannot find any vaccum...


If it also happens when you put it in drive with the brakes on and try to accelerate, it's not a rolling problem. Sometimes as the engine accelerates, it lifts up against the motor mounts, and wires going to the firewall may lose connections. Try gently pulling on the wires behind the motor while it's idling to see if it gets rough. Think simple!

1998 tacoma 3.4L sputters then clears up shifting through the gears


Check the throttle positon sensor on the throttle body. You can do that with a meter. Your idle air control turns off when the truck heats up and is the reason you are noticing it more after it is warmed up.

Ford explorer p0059 code


P0059 .02 sensor heater control circuit draw. 02 heater resistance What this means is the 02 is shorted or open or ECM . 2nd bank sensor one. What concern me is rough accleration,either the ECM subsituted a value to protect the catalytic or you do have a engine miss and P0059 under rationality ,logic appeared.I have to say your solution is to replace 02 sensor on the second bank.To find the second bank stand in front of the vehicle the valve cover closest to the front is bank one the valve cover fartherst from the front is bank two.

I have a 1997 Mitsubishi Galant with rough idle and no power when accelerating. Replaced spark plugs, distributor cap, rotor, spark plug wires, MAF, both oxygen sensors, air filter and the engine still...


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.
