Ford 2001 Focus Z tech 2.0 L Engine idle is too high.
Replaced the timing belt set TDC and Cam as per Haynes manual. Started engine idles at 2200prm if step on gas goes up to 3000 slowly comes back to 2200. Diagnostic unit shows no codes. Engine trouble light is off.
Do I need to ****** the timing? Thanks Vili

this is a time consuming process
need to remove the covers on the driver side of the engine to get to any pulley and in some cases also the engine mount
if so u need to support the engine from the bottom with a engine jack and then first remove the mounting to get to the covers bolts
also keep in mind that when loosening that pulley the timing belt will also come loose so before loosening an pulley u need to get tdc first and mark your cam and crank gear if theres no marks to be able to get the correct timing set again or you will hurt something in the engine
Hello! I'll need a little clarification...What is the sub-model code?...LX, SE...etc...Have any after market performance products been installed?...Was there an over heating problem before the timing belt was changed?...Lastly, does the engine idle and accelerate properly?...
there is no marks!you need special knowledge and tools to timing a zetec engine.try a haynes service manual but is difficult!the cam pulleys sitting on cam shafts with conical joint!without any safe pin or tooth etc.the timing needs to lock the cam shafts and the crankshaft with two special ford tools!try to go on a good garage!!isnt so expensive.a ruined engine is the most expensive repair!
your valve tiiming is way off. you didnt work counterclockwise installing the belt keeping it under tension. and pay close attention to cam positions the half moons face up pic here
now for the correct position of crank pulley
here is the full way to do it just make sure you start at crankshaft working counterclockwise keeping tension on belt as much as possible and when finished always turn engine 2 revolutions with a wrench on crankshaft bolt and double check the alignment before putting back together. but here is the link http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c152801ecf2a
You have to leave all of the slack at the tensioner. Get the timing marks lined up on both of the cams and the crank. With the slack left at the tensioner, release the tensioner. It is okay if the marks move a little after this. Manually turn the engine crankshaft twice and then MAKE SURE THE MARKS LINE UP! If they do after two revolutions of the engine, you are good to go. This applies wether or not you are at DTC or not! Remember that!
Please remember to rate this solution.
put the crank at TDC and the cam gear and TDC slip the belt on adjust the tensioner and then rotate the engine two times make sure the timing marks are still lined up then put it back together and try it if you have the timing off it wont idle right and if could also be the throttle positioning sensor
