2009 Lexus IS250 (Need Help ASAP)
2009 lexus is 250
Didn't start it for one day then next day went to start it it started having rough idle so shut it back off then back on then it started normal. Then today I go for start it to go to work then rough idle came back and this time black smoke appeared now car won't start back up again. I already had the motor replaced due to carbon build up about 6yrs ago. Now this what you lexus members thing is the problem like to find out first before I call my local lexus and tell them the situation thank. Really appreciate it!!

Well it's some sort of over fueling problem. If it's not a consistent problem it becomes harder to diagnose. Sticking injector is possible, bad spark plug maybe. Have you tried to read any codes from it yet? That's the best place to start is with an OBD2 reader.

I had a ford expedition that I knew was missing in a cylinder and my code reader would not pick it up either because there was now cel. I HAD to take it to ford so they could put it on their expensive machines and tell me it had a misfire in the #6 cylinder. I told them to button it up and I would fix it. I still payed the $100 diagnostic fee but had no other choice.

im telling you its most likely your fuel pressure sensor mine did the exact same thing and its a common issue with the is models the pig tail is on the driver side of the car back side of the motor if you unplug it and try and start the car it may take a time or two for it to start but it will and run in limp mode

yea i replaced the sensor never really thought about trying to plug it back in to see if it would work again tbh it only takes about an hour to do the whole replacement

Mason123 does the intake manifold have to come off? Or is there another way to get to it on the bottom of the car? Let me know asap as I will be doing the job myself thanks in advance really appreciate it!!
