Hello everyone I was wondering if I could get some help... I have a 1999 Lexus ES300 (1MZ-FE V6 Engine) it currently has P1133, P1153, and P1349 stored. I believe P1133 and P1153 have been in there for a while and were not giving me the current trouble (this air/fuel sensors were replaced previously but afterwards the codes came back). Anyway I was driving the car about a week ago and it started to feel like the transmission was slipping, it wouldn't go into Overdrive, it would idle rough, and the brake pedal would "harden" at stop signs. So thats when I pulled the P1349 for the first time (along with a few misfires) so I grabbed the TIS diagnostics sheet and started to work my way through the list(at least the easier things I am able to quickly able to do, affordably). So I install a new ECM and a new Camshaft position sensor to no avail. I then replaced the OCV Filter(which didn't look blocked up it had some particles in it and a "goop" of oil came out when I pulled it out but thats it). So this morning I pulled out the OCV to test it and the resistance is 7 ohms and the valve still operates perfectly. So when I go home today I am going to put the OCV back in with a new O-ring and change the oil and take it for a ride and scan it again. I doubt anything will be fixed as both parts looked fine but its due for an oil change anyway. So now I am kind of at a loss as to what to do... Any ideas would be appreciated! Thank you for reading! :-)
