Hesitation

Hi Group,

Thanks for all of the resposses concerning my idle problem.

I have one other problem that i can not fiqure out.

The car has a hesitation at wot around 4200 rpm, if i ease off the gas it will go past.

I ran the koeo, koer and memory and get a code 34, 94, and 44.

I replaced the evp and still the code comes up, I also cleaned the egr.

Code 94 and 44 have been there since i bought the car 2 years ago, and from what i read do not think thats the problem.

Any help would be appriceated.

Thanks

Chris

Oh one other problem the car idles clear, but at about 800 rpm and can not get it lower without the idle going up and down again, Any suggestions?
