porcupine73 Posted May 26, 2007 Share Posted May 26, 2007 Uh...could be just about anything. Is the vehicle in proper tune? You know, fresh filters, plugs, wires, etc.? Quote Link to comment Share on other sites More sharing options...
newg Posted May 27, 2007 Share Posted May 27, 2007 interesting....my OBW is doing the same thing.............mechanic said a bad tire but I am having a hard time buying that one..... Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted May 27, 2007 Share Posted May 27, 2007 Step 1 is make sure all maintenance has been performed, plugs, wires, filters, etc. OEM plug wires should be used. Make sure coil contacts where they plug onto the spark plugs aren't erroded. Quote Link to comment Share on other sites More sharing options...
Jimmyowensfan20 Posted May 27, 2007 Author Share Posted May 27, 2007 OK....after going over and over engine looking for vacuum leaks,intake manifold leaks, checking cat"I got a hole knocked through the middle now". I pull the timimg cover and my driver side cam is now somehow 1 tooth off.. I guess when I got on the interstate yesterday...since this is when it happened...4800 rpm's was enough to jump it....considering I changed it 4000 miles ago I'm wondering if the tensioner is bad...But man let me tell you.. You got to put it in a vice to collapse it and put a nail in it. Oh well...shouldn't take more than a few hours. any tips to make it easier to get the cams to line up and stay lined up when putting belt on?...It took me like an hour to get it on and tight last time.

Jimmyowensfan20 Posted May 27, 2007 Author Share Posted May 27, 2007 Oh! I think I'm gonna have to put motor mounts or tranny mounts in it or something.. It has a hell of a vibration that is being magnified by the miss! Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted May 27, 2007 Share Posted May 27, 2007 Do you have an AT or MT? I've heard using wooden clothes pins can be helpful in holding the belt in various places while lining it up. Maybe you need a new tensioner? I think EndWrench said it should take least 3 minutes and maybe as long as ten to compress the tensioner slooowllllyyy.

Jimmyowensfan20 Posted May 31, 2007 Author Share Posted May 31, 2007 Timimg belt not culprit! after taking out radiator and fans and draining cooling system and pulling belts and covers and balancer i find that my eyes were deceiving me in looking down on marks... sp after going back together with it...I start checking spark and fuel....low and behold a fuel injector isn't working properly so I pull it out clean it up. put it back in still missing! so to make sure that the fuel injector is the problem i switched it with another one on the other side of the motor and the car runs great! leaving it alone and I know if the cylinder with suspect injector starts missing what the problem is... I can't believe it took me 3 days to find the miss and 10 minutes to fix it...for now. Quote Link to comment Share on other sites More sharing options...
