nesre84 Posted February 27, 2004 Posted February 27, 2004 I've had my 93 lexus es 300 for over a year now. It has 152k miles, alot of the parts on it are from a 95 lexus es that I use as a parts car. The transmission blew 4 months ago, so I replaced it. Car was fine for about 2 months then the engine started to idle very rough. Then It started to stall everytime I stopped unless I put it into neutral. Had it "fixed" by some friend's of my father at their auto shop. Didn;t stall for about 2 weeks and now its started to idle very rough and stall occassionally. The engine has the most trouble idling while on an incline. I'm pretty sure it has something to do with the fuel intake because its worse on inclines and when my fuel is low, but replacing those valves is quite costly. A new transmission set me back enough. Any suggestions on how to fix this problem.
slstsang Posted February 27, 2004 Posted February 27, 2004 i had similar problem, but i changed the pcv valve and that fixed it..... so check that and also the fuel filter....
