i'd trace your egr and vaccum lines. the egr is prolly not working correctly or you have a pinched/unhooked line somewhere.

we pay 35 bucks for an e-test here. if its cheap there as well, just take a chance and try it. typical e test tricks that apparently work are, higher octane fuel, bring it in hot, new plugs and wires fresh that day etc etc. i'd say just try and go from there.

Ok...on this subject...it turns out that the plroblem with the check engine light was the crank sensor....even though the engine was running well ...the crank sensor was causing a 0300 code.... after a while the engine would not run...it would just shut off...it was than the it was throwing out crank sensor codes...changed it and no more trouble.
