Question about 2003 Ford Focus

2 Answers

Severe hesitation, bucking

My 2003 Ford Focus is hesitating severely at all speeds and at idle. Emmissions light has been on for a while and will start flashing a bit then remain steady, does that the whole time. We have changed spark plugs, ignition coil, one O2 sensor, cleaned maf sensor, and did check on dpfe sensor. I am completely confused. Please help.

Change the plugs and the rotor insode the distributor. Sounds like your focus has either a hole in the Rotor Button, a cracked rotor button or the plugs need to be changed. Anotehr thing that would make your focus stall, **** and generally be a pain in the **** is: Fuel injectors out of hole; bad fuel injector; bad gasoline; Air filters need changing.

Those are basically some of the things that cause the Focus to jump and ****.

Sounds like the cat may be blocked. Stand at the tail pipe and get someone to rev it. If you get a whooshing sound from the exhaust, investigate further up the pipe.

My 4runner has a slight hesitation while warming up.


You have several options that could be the problem. Check idle speed sensor, check tps sensor, I would suggest to get a diagnose from the E.C.U to find out that code you get. Good luck

My 2000 1.6 ford focus hesitates when driving from a standing start


Is this when the engine's cold? check the auto choke

when it's warm -air ingress to inlet manifold - listen for air noise - you will also notice that it will hesitate when you accelerate
also check if servo vacuum is affecting the engine speed - when idling pump brakes if it is this then speed increases
Air intake sensor unit Now you need to get a garage to plug into the ECU [car computer]
