Very frustrated!
 
[:(]
ok so I have a 2000 se sport so carfax calls it...2.0/ 16 valve zetec / DOHC/ power windows, door locks and mirrors...it has an issue no one can seem to figure out...first of all it throws absolutely no codes.....it has a MAJOR hesitation, bucking, jerking problem under 2000 rpms...once past that point runs fine..If the A/C is on, it will stall out if going slow and will stall if at an idle....I've changed the tps, spark plugs, fuel filter, Ign. coil, cam shaft sensor and crank shaft sensor.....what could it possibly be?...The fuel delivery module was replaced as per the recall....gas mileage is still pretty decent...the alternator went and I just had it replaced and I was hoping by some miracle that may have been the problem...this issue has been going quite some time and I don't think I can go another summer with no A/C here in GA where it's already in the 90's...i was told maybe the Idle Air control...any thoughts on that part or anything else it could be?...I've already put way more into the car then I paid for it and can't keep doing it [bigcry]...hoping it's something so simple everyone just over looked itů
Thanks in Advance....Colleen

one other thing I forgot to mention...if I put it in drive , keep my foot on the brake and step on the gas, it sputters and pops and backfires under the hood..Not sure if this issue is related to the one above or something totally different. [bigcry]

Try cleaning the idle air control with carberator cleaner along with the tb. They tend build up a bunch of gunk.

What brand sparkplugs?
Motorcraft are recommended and tend to be the best option.

I wouldn't think anything you've replaced would have any bearing on the problem. Not sure who told you to replace all those things but, I would have more caution listening to them.

Has the A/C been serviced?
If not, it might have some bearing of the 'sputter'. Low system pressure can cause the compressor to cycle more often. Possibly often enough that the IAC can't compensate fast enough.


Backfiring and such sorta sounds like you may have a vacuum leak or the cam timing may be off. Has the timing belt been done?
It's possible whoever did the work didn't get it quite correct. This is something you can check yourself rather easily. Simply bring #1 to Top Dead Center, remove the valve cover and see if the slots in the drivers side of the camshafts line up. If they don't, cam timing is off and will need to be fixed.

Also, one of the sponsors has a scan tool loaner program that you might want to look into. 1turbofocus is his screen name and there is a thread floating around about his program, Xcal loaner program in the search box should turn it up. It's free professional help and well worth your time.

X2!! Also check your pcv/hose and booster hose, they collapse over time.

Do a search and see if a local member has a xcal so you can do me a datalog , Sounds like a fuel issue

A local mechanic who I've been going to for years changed all that stuff for me...AND he changed the timing belt for me...but I don't remember having this problem right after he changed it a few years back..this has been going on now for the past year...anyway, I will get second opinions from now on....I do remember someone saying it could be timing but then I also heard if it was the timing it would run bad all the time...UGH!! I AM SO CONFUSED! especially cause I really don't know much about cars....I will print out your response and see if my brother can check it out for me...first though, I will try the easy approach and clean the IAC if I can find it...I have to try and find a picture of where it is... <sigh>....thanks

By fuel issue you meant fuel filter? Since it is under 2,000 rpm's...

IAC is on the bottom of the intake manifold although I don't think that's the culprit.

DrkKnight614 06-01-2012 04:55 PM

Posted via FF Mobile Ya check the PCV hose, those are a known issue. Was the battery changed or checked? Maybe check your battery connections. Make sure your intake system is clean. Take out the MAF sensor and spray it with MAF cleaner. Make sure the connection is good too. I assume its had an oil change. If non of that works, maybe run a carbon cleaner through your fuel tank and your engine, like Seafoam. Keep us updated Colleen. The focus really is a goodcar and so much fun to drive. People love them, we would love to help and see you driving your car.
