i have had my truck in shop several times for diagnostics check and each time something else comes up bad.when the parts are replaced there is no differance in performance.it does the samething or worse.have replaced the mass sensor,02 sensors,tps sensor,ect sensor,pcv valve,spark plugs and wires,iac valve,fuel pump,fuel filter and fuel pressure regulator.have been thru all vacum hoses and they found no leaks.and truck is worse now than it was.it stalls when idoling,sometimes it dosen't start when hot.after i push clutch in and put it in gear and let the clutch out to go the engine won't rev up and go.push the clutch back in and it will rev up(sometimes it won't rev up then either) several people told me it could be the PCM even tho it didn't show on diagnostics check.what do you think.
