TheMeatWagon Posted July 30, 2004 Share Posted July 30, 2004 Okay so i finally did it... got my first car which just happens to be a soob. 1986 subaru gl turbo coupe... 5 spd d/r tranny. The engine has about 34000 miles on her. Okay so shes fast and im lovin her hardcore only one problem i can so far detect. She idles rough as hell and when going it seems to misfire. Im thinkin either to much gas or not enough or not enough air... perhaps problem with vacuum? The guy i bought it from... Shean aka The Scooby... took off what i think he said was a gas cutoff regulator... something like that. He said it just makes it so now the car doesnt cutoff gas after a long drive. Could this be making vacuum just floppin around with nothin pluggin the end? I was also thinkin maybe she needs new spark plugs. He threw in some brand new ngks so ill pop em in over the next couple days. Also he said the rough idle was because it wasnt warmed up and we took it for a drive and it seemed after it got warmed up that it was true because it seemed to idle just fine after that... but it cools real quick and starts all over. Dont get me wrong i love the car and would do it again in a heart beat but this idle and misfire is driving me nuts... Anyone had this problem or could possible help out? Thanks in advance.

TomRhere Posted July 30, 2004 Share Posted July 30, 2004 Congrats on the ride! 1st thing I would do is install new plugs, wires, cap & rotor. Then I'd replace the fuel & air filters. Would also put some good fuel system cleaner in the tank. I normally do all of that, plus hoses and belts, oil change, and whatnot whenever I get a "new" used vehicle. That way, I know when it was last done:) Checking for vacuum leaks is another good idea. Could be a faulty Coolant Temperature Sensor too, as it's giving the 'puter some faulty info on the actual temp of the engine. Link to comment Share on other sites More sharing options...
TheMeatWagon Posted July 30, 2004 Author Share Posted July 30, 2004 Thanks man. The new plugs wires caps and rotors will be comin today or tomorrow. Fuel and air filters i will try too. Im going to try to get some fuel injector cleaner today as well. The hoses and belts and oil change Shean did all of in the last couple days. How would i go about seeing if it is a faulty coolent temp sensor? Thanks again. Link to comment Share on other sites More sharing options...
nutt7 Posted July 30, 2004 Share Posted July 30, 2004 congrats on the car! to check your coolant sensor you should disconnect the wire clip (sensor stands vertical, on the back side of the intake mani, passenger side, its kinda down there a ways) and with an ohm meter, fix the probes on the sensor leads and, with a cold engine, start it and monitor the resistance. It will decrease as engine temp increases...i will post the actual values later, unless someone else knows them, but without a water temp gauge that actually shows temp, it will be tough to judge. more times then not, from what Ive read, its just the connection at the clip that needs to be cleaned with electric contact cleaner. (try this first) hope this helps! eric Link to comment Share on other sites More sharing options...
