Still a slight rough idle
65

Asked by ammo284 Jun 25, 2007 at 05:19 PM about the 1985 Chevrolet Suburban

Question type: Maintenance & Repair

I changed the carb...the holley was leaking gas at the secondary...also had a stuck float....not bad for a new carb.
The new holley works better and doesn't leak....just did a complete tune-up and oil change....this is a rebuilt engine (350 small block)
with 25,000 miles on it....I'm wondering if their is something internal that may cause this problem.....HELP!!!!!!!!!!!

Follow these steps after opening the following link http://www.autozone.com/UseCase,S001/UserAction,viewSimpleDiagInfo/Parameters,info/getInTheZone.htm 1. Click on "feels" 2. Click on "Idle Is Rough/Erratic" 3. Click on "engine idling" 4. Click on "engine compartment" It will give you a list of components to trouble shoot. Sorry about the process, it won't let you link directly to the page.
