http://www3.telus.ne...ifications.html You are way out of the power band when you over rev it like that so of course
you have no power!! Eventually you will have no motor either if you constantly rev it that high!! It is a torque motor not a ho mustang 302 or 6
cylinder if you like the sound of screaming rpms you should get a small v6 or a honda. Try cleaning the Iac and adding some gas line dryer, Be
sure to keep the solenoid deal up when you spray the Iac valve out you do not want the crud to flow into the solenoid motor!!
86 BRONCO 302FI auto 3.73:1 33x12.50 15 AT
If you have a fuel related issue run a triple dose of dedicated
gas line dryer, before throwing money at it!!

When the going gets weird, The weird turn PRO!!hst

Parts replacement is not trouble shooting, replacement follows trouble shooting

Broncos are MPVs not SUVs

Engines run on fuel, or steam

Motors run on electricity, hydraulic fluid, vacuum, or air
