I’m having car problems. I have a 94 Metro and it idles at 2 grand until it’s warmed up, then it fluctuates between 1.5 and 2 grand every time you engage the clutch and after about a minute it levels of at 2 grand again. I've checked all the obvious things it, I’ve checked for vacuum leaks using WD40, their are no plugged injectors, and fuel flow is constant and there is no trouble light coming on I know it’s not a gasket or vacuum leak if you know any thing about vacuum when you spray it with wd 40 it will affect the engines rpm making it go up or down. I know it has electronic parts that can affect the idle process. I can’t afford to take it in and have the car hooked up and analyzed that’s why I’m trying to narrow down the problem if you can help I would gladly pay you but I need more than a generic answer. Any Ideas?
