sick car
 

I have Mazda Capella SW body number GWEW 2000 Sr motor. The problem is it idles very rough and is lacking in power when you come to a stop it will cut out. Has got progressively worse.
Had it at a mechanics for two weeks they tried air flow mete, changed the throttler body, checked for air leaks around inlet manifold,check injectors even drained the fuel tank and replace with new fuel still have the problem the only problem was vacuum was down to what it should be. Could anyone give us idea's what else it could be. Thanks.
