Any info would be helpful. 1996 ES300, 1MZ-FE motor. Today we got down to changing the bank 2 knock sensor. Changed knock sensor and put everything back on and now the car won't run at all. It starts briefly then just dies out by itself in less than a minute. Also the gas pedal seems to make the car die quicker. Actually the second I touch the pedal the rpms shoot down and the car dies. Checked for loose vacuum hoses and leaks and didn't find any. It seems as if the car is getting too much air, if that makes sense... Can anyone please advise? Also I followed these directions: http://www.findonefindall.com/toyota-sienn...nock_sensor.htm and some others from alldata.com.

Problem Fixed guys. The wire that comes from the engine and connects to the coil pack was broken apart inside, the connectors weren't making good contact. It kills me that it was something this small and obvious but all in all it was a learning experience. Thanks to all those who gave me insight.

Not missing, I only have 3 coil packs and from those goes a wire to the back 3 cylinders, here are some pics for reference to what I am talking about. Also if you have a 95 or 96 ES, pop the hood and see for yourself, its hard to explain even with the pictures. And for the life of me I still can't figure out the problem. I am now torn between the fuel injectors or a blown cylinder... Ok, so I am more confused then ever, I looked at a repair manual for my car and it also said there are 6 coil packs! I only see 3 in the front the 3 back cylinders only have a wire going to them in my car. Plus my firing order is different from a normal 1MZ-FE. Does anyone have any idea whats going on?

But I have a question now, how could it be that I'm not finding the right one because the CEL says Cylinder 1 and thats 1 of the 3 that I changed. The only thing that goes to cylinder 1 is a wire from a coil pack that sits on the 2nd cylinder. I honestly don't know what to do anymore, even the mechanic is unsure, I am going to try another MAF and I'll go ahead and change the last coil pack but I highly doubt that those will fix it. I am beginning to give up on this...

Ok guys changed the MAF with one from a junk yard, a new was running $225 in Autozone in NY. Still not solving the problem, do you think that I picked up a bad MAF from the junk yard? Car now seems to be a little worse... Anyone???

Just got it checked out today by my mechanic, did the compression test and all; said that the M.A.F. sensor has gone bad. What do you guys think? Also he said a new one can run about $400.00

Well I changed the outer 2, and I tried to swap and switch and know that the middle one is not bad (the old one). If I pull the wire off the pack is still sparking, that means that it should be good right? And there is no rear left coil pack, there is the wire which I did change. I also thought I might have got a bad plug when I bought new ones so I bought one more and put that in and still no luck. Also I heard that its Very rare for all 3 coil packs to go out at the same time. Also as a side note, my firing order is different, when I set it up as the diagram it was barely starting, also I did get my firing order checked out and it is correct, just not like the diagram. Any more advice? Thanks for all those who did help.

How would I go about changing the injector? I wanted to clean them out at least but I cant seem to get them out, I know that they are located under the Lexus cover right above the first 3 spark plug cylinders and got the wire connector off them but cant get the injector itself out, any advice? Thanks

20 y.o. with a 1996 ES300 Coach. Got the car when I was 16 with 95K, it now has 175K. Absolutely love the car. Going into my third year of college now, and am looking forward to a newer Lexus soon!

Ok, I am going to try and sum it up the best I can, but I can't figure this problem out. 1996 ES300 with 175K now. Car ran perfect until last week. The car ran fine one day and the next day it throws a check engine light and starts hesitating bad, followed by the CEL flashing. The next day I went to Autozone and had them run the code, it turned out to be a cylinder 1 misfire. Based on that I got new spark plugs and wires, along with a fuel system cleaner. Got all that put in and it was still hesitating and throwing the flashing CEL. Then I noticed that my air intake tube was cracked and splitting, so I got that changed, and still the same problem. Next I got 2 out of the 3 coil packs and changed those at $75.00 a piece. Still nothing. I have probably spent around 2-3 hundred with no progress what-so-ever. I will say that the hesitation decreased but its still there. Now people are telling me it could be a vacuum leak or injectors, I really want to figure this out on my own as it doesn't seem like a huge problem but I am not too sure at this point. Any advice would be helpful, I am going to check it out again tomorrow morning but if nothing works I will have to end up taking it to a shop on Monday, I am in college and need a car, but I'm also on a budget which is why I haven't taken it to a shop already. If anyone needs me to clarify something please do not hesitate to ask. Thanks.

Searched through all the threads and couldn't find a fix for my problem. I have a 95 LS400 with the Nak system and the 6CD in the glove box. Worked perfectly until yesterday when" ERR 14" came up on the display. Also when i try to Eject the cartridge, nothing happens, until i shut the car completely off then it pops out. It wont eject when the car is started, it only ejects when the car is off and you push the button. Nothing is jammed inside, and i pulled out both Radio fuses in both the driver kick panel and the engine compartments and still no luck. Anyone please advise, Thanks.

Thats what i orignally thought since I live in NY, the only thing that really stops me from buying an ES330 right away is the all too common transmission problems. I like the GS because of the room and power, but I dont like the gas mileage. I am going to try and test drive both and see what happens. Keep coming with more feedback guys! Thanks

I have been doing a lot of research and am getting a new car soon, Lexus of course. I am trying to choose between a 05' ES330 or a 03" GS430. They both have pros and cons, just wanted more input from helpful people. Thanks
