asked by on January 18, 2018

At times my car has been sputtering upon rapid acceleration and feels a bit hesitant. If I back off accelerator and reapply, it fixes the problem. I noticed a large puff of black smoke coming from the exhaust pipe one or two times during rapid acceleration. Today I started my car after work and the engine was immediately reving as if my foot was pressing gas. I turned car off and restarted and the problem was gone. However now my malfunction indicator light is on. Any idea on what this could be?

My car has 29000 miles.
My car has an automatic transmission.

It is very possible that your engine could be burning oil. This could explain why it’s running bad as the engine would be getting too much "fuel". This will cause the engine to run roughly as the air/fuel ratio is incorrect. I would recommend having your vehicle inspected by a qualified professional to determine the exact cause of this issue.

Your car doesn't have a timing belt, so it's not likely that it has "Jumped time." But if the car was low on coolant and overheating, it doesn't take much driving to do some engine damage. So it could be...

2005 Ford Escape v6. Had a bad A/c compressor. So I replaced with a new one. Added my 4oz of oil and can not get the clutch to engage (i will jump it later to add Freon) in the meantime I noticed the radiator fans are not kicking on (they were working previously to the A/c compressor being replaced). To diagnose to radiator fans I have checked the fuses and they look good. 8 also replaced the relays and jumped the fans to the battery (which they do come on at that point). So my next step was to replace the temperature switch sensor, which I did and the fans still are not engaging. I feel like I have done everything I know to do and still can’t come up with an answer. Also note previously to all of this last year the heat was not blowing as hot. At that time I back flushed the lines and added new [coolant](/topics-coolant-ford/). The heat worked a little better or so I thought. But again with all that is going on now the heat is not the best again, which is one of the reason I thought it was going to be the temperature switch that was bad.
