perhaps the coil is weak? or maybe you got a bad plug or wire.

Replace AC Compressor, Accumulator, Orifice Tube, and Hose Assembly


Made a video on how to change the AC Compressor, Accumulator, Orifice Tube, and Hose Assembly on my 2003 Ford Focus 2.0L SOHC SPI. Symptoms started off as blowing hot air at idle and then it just blew hot air all the time and Firestone told me it had not compression and needed the compressor replaced. I got all my parts at AutoZone for a around $230. Save 20 On Online Ship To Home Orders Of 100 Or More

Rough idle while in park, cutting out on highway


It could be something as simple as a vacuum line,but sounds fuel related. Possible pump.get a fuel pressure reading done and if pressure doesn't hold.....suspect fuel pump

I have 2003 ford focus 2.0 SOHC SPI with a bad missfire


Yup, been there, done that. Found it was a bad injector. Replaced that one injector the test showed and runs great now. Check engine light should be on though because of this problem. The test will show you which cylinder is misfiring and that is the injector you change. My test showed #5 cylinder. The last # in the code read.

My 2003 Ford Focus dies when idling after a little road trip.


have the check engine light checked at a parts store its usuall free. I would bet its the idle air control motor. This controls the fuel air mixture at idle

2000 ford focus w/ 2.0L on cold start-up runs ruff, idles badly until it warms up


Could be a problem with ECT (Engine Coolant Temperature) sensor or fuel injection system. Will need to test and check in order to discard.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

92 Ford F150 4.9L. starts good, idles rough, dies at slow speeds


4.9 litre ?? you having a laugh its a 10ton truck engine not a pick up -global warming machine,remove the pump/sender unit and check the gauze filter also look inside tank for a something floating around ,i think the idles is not a related problem to the vehicle losing power but their is a possibility you could have a problem with the little vac operated thing on the fuel injector line that allows the fuel through only when the engine is running
