Hey guys so im having a bit of trouble here figuring out the problem with my 92 ls400 just bought the car 2 months ago. so i was driving it to work a week before and my engine died at a light figured it was because of my subwoofer cause a short. so i waited 2 minutes started it back up drove it too a friends parked it let it run for 10 minutes didnt see any issues drove too work fine. 2 days later was driving it onto the highway felt a little power loss as i was accelerating around 2000rpm after 3 it was fine so i continued driving got too the mall let the car sit for a couple hours came back out started it let it run for a bit then drove back towards home engine died completely even with my foot down then wouldnt start back up towed it back to my house let it sit for two days then tried to start it it started up it started but now idles below 1000 rpm revs up fine as the rpms kick back down it shudders a bit no idea whats going on also coolant light just came on
So a friend of mine was helping me clean the throttle body and he accidentally broke a really cracked hose, so he tried to replace it. Since then I have been having this weird issue where I am idling at 1,100 RPM's until the car starts to get hotter.
Attached is the image and you can see the hose that was replaced with non oem parts, kind of rigged up. What is the black plastic cover and what are the three hoses that go into it? I am trying to replace all three because they are all sort of damaged just from the heat over time.
So basically here is whats happening. I own a 1992 es300 with 112,000 miles on it. I bought the car about 3 months ago with 105,000 miles on it. All in all its a pretty decent set of wheels for a poor 22 year old college student, however it has a couple of problems. The primary issue is this. When I stop at a light and the car is idling it will idle at about 750rpm, however after idling for a couple of minutes it will drop to about 500rpms, and this is when a single misfire occurs. The misfire is completely random, and sometimes doesn't happen at all, however i noticed when the A/C or heater or just the fan for the vents is on, the misfire seems to be more consistent. The car does not misfire while driving, only when idling or after freshly shifting into gear. This problem is driving me crazy, Ive replaced the O2 sensors, the spark plugs, and got a complete tune up done. There is no check engine light. Ive done a ton of research and from what I can tell it is either the ignition coils failing, or something to do with the fuel injectors. But before i shell out more money that I dont have I was wondering if anyone has any opinions on the issue or has experienced a similiar issue themselves? Also i feel it neccecary to mention the transmission is slipping, not all the time, but sometimes it does slip, im taking it to get looked at next week. Its a great car and honestly Id hate to get rid of it so soon.Thanks in advance for anyone who responds, i really appreciate it. Also I read on here that i should be using 91 octane fuel instead of 87 is this true?
First time poster, long time lurker and I was hoping I could maybe get some help from you all as I'm running out of ideas.
I'm having some RPM/shifting issues with 08 ISF. Here are the symptoms so far:
Unnaturally high RPMs in Neutral/Park whether on a cold start or after being warmed up. Drop back down in Reverse/Drive. Standing
up hill, if I put the car in neutral and let off the brake, it wont
roll back until I tap the gas. It will then rollback for a second and
then stop once again. RPMs have to go much higher than before to shift into 2nd, 3rd, etc gear and the car jerks during the lower gears. When
in bumper to bumper traffic the jerking is much more noticeable as the
car keeps shifting between low gears. (I drive in chicago traffic into
the city for work so it gets old quick haha) Under wide open
throttle and then release the RPMs will drop very quickly but then once
they hit 2-3k they will hang and bounce up before going back down. Never
did this early on when I bought the car. When releasing
throttle, the car decelerates very slowly and wont come to a complete
stop until the brake is fully pressed down and brake has
pressure/pushback even when at a stop and car will lunge forward
slightly when brake is released. Here's what I've checked/had done.
Replaced throttle body, problem continued, put old one back. Checked for vacuum leaks, apparently none. Had transmission reflashed at dealer, same problem. Had ECU reset, same problem. Had data logged/read for an hour, nothing out of ordinary apparently. Only thing that's obvious is that one of my cats is a bit clogged but mechanic friend said it shouldn't be causing it. Also said MAF should not be issue either. No
idea what it could be and it's been driving (haha a pun) me nuts. It's
my daily driver too so this worries me every day. To top it off, no
check engine light so I'm completely in the dark!
Thanks in advance everyone! Hope I can figure out an answer soon.
