Re: 86' Chevy Pickup: Auto-305
*Please Note: Work Done*
Engine Rebuild: 04/2013
Carb. Rebuild: 09/2012
Tranny Rebuild: 02/2010
She's been running rough for a while now and I was hoping it wasn't the tranny again but really thought after the engine rebuild it would probably address the issues, but that was not the case.
Main Problem:
Almost every time going down hill, I usually allow the truck to coast all the way down, and when I do go to apply the gas, instead of accelerating it just Revs-up real high. If Im lucky, sometimes I can take it down to 40-45mph and itll smooth out but usually its just a rough ride home(Hesitation and "Over-Revving").
**down hill is where I notice this most, however its happened on straight aways and the freeway as well.
Ive also noticed the carb. is running slightly rough/lean
And just yesterday, driving 55mph the truck began to hesitate, so I let off the gas, got down to 45mph and it was fine. However today I found out if you keep on it at 55+ the truck shuts off/stalls!
Been reading that it could be a Mass Airflow Sensor(MAF) issue or the equivalent? Does this yr./mdl even have a MAF, if so, where is it located?
Maybe the Cat. Converter? I don't know!! ????
Please Advise.
