erratic idle,almost stalls still after all my work

[broncokenny]

Yes this is broncokenny (the one with **** problem)after a lot of work and money.Bronco still

sometimes not always will idle funny as high as 2000 rpms down to less than 750.Ive changed

everything I can think of coil,ign mod.,cap rotor,plugs and wires 1 1/2 yrs old,egr valve,sensor/switch

checks out ok,removed catylitic conv.,inline fuel pump,filter,throttle TV cable,throttle AI,still nothing works is there a computer that runs fuel or idle?What next? Took it to 3 different local shops all failed in ther diagn.Im

afraid to buy reader,that it will send me on another wild goose chase,this engine was rebuilt by a couple of

boys in AZ.,they did a good job but I dont know what they skipped or kept during rebuild.It does

sound great now with out catylitic conv. and glass pack has great pick up now.Sounds like BAD

MOFU. now. $-)

[steechfinger]

the map is on the left of your engine on the firewall and the a/c condenser it has a vacume line going to the intake manafold and a electral harness its mounted to the heater motor it cost like 70 bucks at pepboys and the throdel sensor is on the throtle body on is it in the throtle body well is there somewhere and its like 30 bucks but have you serviced ur tranny lately that could be what is causing ur jerking but who ******* knows let me know if any of that helps
