Jerks when accelerating SolvedSolved

Ford Escape 2003  135000 miles
After a service was done to my car, it jerks when accelerating considerably. Every time it does so, the alternator light appears in the dashboard but it has no charging issues. The scanner registers a crankshaft's sensor failure. I've disconnected the exhaust, cleaned injectors, checked coils and hoses and even changed spark plugs but the problem is still there. Any help?

I have been told that by changing all the coils the problem should be solved. If the scanner detects which of the cylinders is having a coil failure you can then replace only the damaged ones. Tell me if I could help you please.

I personally believe that your problem is that your car has not been washed with a carburetor cleaner when the tune was made.

I had your same problem and the cause ended up being an ignition coil. Once it was detected which was the damaged coil with the code errors in the dashboard, it was replaced and the problem was solved.
