nolanuffsaid Posted October 31, 2007 Share Posted October 31, 2007 Sunday it all started Sunday nite. me and my girlfriend ( the lexus is for her ) were driving down the hwy. we pulled up to the red light and we were talking, when she looked down at her gauges and realized that the car had shut off unexpectedly. we tried to start it again, but when the car turned over it would start but immediately shut off. so we tried again and again but still the same result. so i asked here to hold her foot on the gas pedal and start it, and it worked. so she sat there and revved the engine a bit, but as soon as she tried to shift into drive the car shut off again. at this point i was threw! she was losing it and i was getting upset too. after pushing the car to the nearest gas station we filled the gas tank up with fuel thinking that was the issue. we were wrong. i managed to drive the car home by holding the gas pedal and starting the car. i would hold the brake shift to drive all the while revving the engine. that was the only way we were gonna make it home. Monday monday after work i talked my boss into letting leave a bit early so i could take a look at the car. after some troubleshooting ( i'm a ok troubleshooter thats why i'm here) i came to the assumption that the fuel filter was clogged. so later i went to the nearest auto part store and bought everything i needed. when i got home i started to change the filter. after the sun went down i couldnt finish so i packed it in and was gonna finish on tuesday. Tuesday i was able to almost finsh the remove and replacement of the filter, but once again ran out of sun light so i would finish wednesday. Wednesday at last, i finished with the fuel filter and went to start the car up to test it out. after trying to start the car a couple times with no success i was done with it. i came inside signed up for this forum and now i'm postiing this message. Can u guys and gals plz help i'm all out of ideas and the misses needs her car for work. thanx in advance Quote Link to comment Share on other sites More sharing options...
zockslexus Posted November 1, 2007 Share Posted November 1, 2007 Sorry to hear about your troubles. I do my own work too, and I am a decent trouble-shooter. However, sometimes you just have to take the car in. Take it to a carx or something where they diagnose it for free. I do that when I just cant figure it out. I wish you good luck on your beautiful car. Quote Link to comment Share on other sites More sharing options...

rfm73914 Posted November 15, 2007 Share Posted November 15, 2007 can u guys link me to the IAC valve cleaning thread Did you find the problem? If IAC fix didn't help, how about the air intake hose...cracked at the gasket and seals under certain positions of the engine but opens with movement. Car is dead when the seal is broken. Hope you are back on the road. Quote Link to comment Share on other sites More sharing options...
