Question about 1993 Mercury Villager

3 Answers

Engine first runs good, but progressive chug/misfire.

The motor starts and runs well, but after several minutes begins to hesitate on acceleration with progressive chugging and misfire, loss of power, etc. Merely letting engine cool down a few hours is not enough to get clean engine start. It neeeds to sit over night I've done plugs, wires, rotor, distributer cap, ignition control module, Sea-foam internal wash with 2 follow-up oil changes, and catalytic converter. Still same problem. Check engine light works, but goes off upon starting engine and stays off indicating no apparent error codes being detected.

    Thank you. I've been following advice of well meaning "motorhead" friends only to get more frustrated and discouraged. I just can't afford to dump "shop rate" labor into this vehicle. You give me hope I'll be able to winter with it another season.

The coil is most likely the problem. As it gets hot it will malfunction

I have a 2002 Dodge Stratus 3.0, when accelerating the engine chugs and engine light flashes. I heard it's a bad catalytic converter, is this true?


A plugged converter will cause a NO power situation where the vehicle is unable to expell exhaust gasses and cause poor acceleration. A flashing engine light is the result of a misfire. ( spark plug/coil/injector/wiring ). The engine should still be able to accelerate but will have a noticeable hesitation while doing so

You have an engine cylinder misfiring, run a fault code test with a scanner to see what cylinder is misfiring. Misfire codes look like this P0301 is cylinder number (last digit of fault code) one and so on.

2002 chevy avalanche hesitates when accelrating and check engine light starts blinking


THE BLINKING MEANS THERE IS A MULTIPLE CYLINDER MISFIRE CAUSING CONVERTER DAMAGE. NOT SURE KNOWING WHAT MOTOR YOU HAVE IF ITS THE 4.2 THERE IS A CAM SENSOR ON THE PASS SIDE FRONT OF THE HEAD THAT GM HAD SEVERAL PROBLEMS WITH. FIND A PLACE THAT WILL PULL THE DTC CODE FOR YOU. VERIFY ITS A MISFIRE AND/OR CAM SENSOR CODE, IF IT IS REPLACE THE CAM SENSOR. YOU HAVE TO REPOSITION THE POWER STEERING PUMP TO REMOVE AND INSTALL THE SENSOR

Misfire, From a cold engine you wont have the misfire. When you engine is cold fuel is in demand and it will run great. As it warms up the fuel strategy is to lean it out (proper balance is 14.1 to 1) . At normal operating temperature the spark plug required KV is 15kv. As you accelerate the sparkplug require more voltage from its coil reserve and it delivers and at the same time the engine demads are high in order to accelerate and the spark will seek the easiest path spark plug, now when you come to a stop the demands for spark decrease and it seek the easiest path where is that at ? out through the boot of the spark plug, The vehicle is equipt with what they call COP (coil on plug) along the boot path it deteriates and so does the coil it deteriates .170,000 mile of hard working COP. they are at their worn stage you can find the weak coil with a cop tool because it misfire on acceration your looking at a boot,probable water got in there shorting it out,if it misses at idle its either water in the boot or the boot itself or the cop.

My truck hesitates and chugs than will clare up


There are several ways about this. Could be fuel filter, water in fuel, ignition part starting to fail(plug, wire, cap, rotor, coil) or possibly even oxygen sensor. The oxygen sensor will clear up if you accelerate heavily then when under normal load it will start chugging again. These are a couple of areas to check without getting into serious diagnostics.
