# A little help diagnosing my bro-in-laws 92 SE...

Posted by dmontzsta (92 SE) on October 07, 2003 at 23:48:57: He was driving home when it starting running rough. So he parked it, tonight I went and looked at it. First thing I did was start it and let it idle, it idles fine, but if you give it gas it is really rough. I then unplugged #1 cylinder and there was a big change (ok it is working) I did it to all of them and they are all fine, I tested the coils with a ohm meter they are all fine. Then I proceeded to code check, I got a 34 Detonation Sensor, so I reset the ECU and came back with a 55 All clear. I checked some of the vacuum lines they all seem to be in tact except it is missing one from the drivers side of the manifold it runs into some sensor then out of the sensor there is a hose that runs right back near it into the manifold again. What do you think? it was too dark and late to hit up the autoparts and get the hose, but would that make it hesitate? Replys: Classic symptoms of a leaking injector n/m abdul (VE) 07:06:18 10/08/2003 (0) I'd have to see which part it is, but bad/ missing vacuum hoses cause a lot of problems like this. --> Matt (93SE) 00:28:02 10/08/2003 (0)
