				Squealing rough idle, help!
			 
			
			When starting the car and usually when in neutral the car idles rough from 200-900 rpms and while doing this it squeals in a high pitch.  Is it a belt problem.  At first i thought it was a vacuum leak disrupting my normal idle.  Its an 83.

			I think it may be a problem w/ one of my injectors.  It might be stuck.  The car doesnt seem to run on all 4 cylinders when this problem occurs.  The guy i bought the car from had the same problem, bought a new injector but the problem stopped so he never put it in.  It has gone away again but its intermittent.  Should i just replace the one injector or do all 4?

			I recommend having all four injectors cleaned and flow tested. 
		
	
		
	
			
			
				
					http://www.witchhunter.com/ I have never used them, however i have heard all positive things about them. This beats paying $100 per injector to replace them with new ones.
