Well yesterday I took my car to a shop to get water pump because my car overheated past 260��.Car was running alright and no SES light was on.So I get my car back it has an erratic idle and SES light goes on and off.Shop claims it came in running like that and that my coolant temp gauge wasn't working.
Anyways I took my trusty scanner and code 23 & 35 show up.How can I get some flow charts to follow?Is there anyway to adjust idle speed on our cars?Also does anyone know of a good OB1 scan I can buy to see what's happening?
