Lexus RX 2004-09 :: Off Idle System Too Lean - Gas Pedal Long Term Fuel Trim Jumps To 29
Have a system lean code popping up. long term fuel trim at idle is 14. No misfire counts. adjusted fuel trim from full rich to lean still no misfire counts. When on test drive and found after accelerating on the freeway soon as i take my foot off the gas pedal long term fuel trim jumps to 29 and multiple cylinder misfires start to occur. I take car off freeway and at stop light can feel misfire and fuel trim still at 29. coast it into the shop and at idle LTFT down to 10-14. Sprayed brake clean all over intake manifold but wasn't able to register any change in fuel trim. Fuel pressure is within spec. Cleaned MAF and Replaced with known good. LTFT still high

I found on internet loads of comment about this error code, but in my case the only bad thing is with fuel consumption - about 9-10 litres (!) for 100 km on motorway. Normaly it should be about 6-8 litres.
The error means: "P1128 is "Long Term Fuel Trim Too Lean". Which means the air/fuel mixture is leaner than the HO2S can compensate for."
Idle is working correctly (i think thats to do with MAF), engine start without any problems and overall car running smooth.
What can cause a bad fuel consumption? Is anything to do with a lambda (O2) sensor or it could be something else?
Prius (2004-09) :: Long Term Storage Of High Voltage Battery
I have an opportunity to get a high voltage battery from a salvage Prius. I don't need a replacement now but thought having an extra battery would be a good idea. How long can the battery be stored? Maybe switch them out every few months to keep both charged?

My car is running great, no issues. I just changed the ignition coils, i was having a misfire. It was easier since i was changing the back to replace them all. My CEL and VSC went on and it is code P0430 bank 2. Before i spend a ton on a new catalytic converter i would like to change the o2 sensors. Problem is, I am not sure which ones to change or where to start. Is this even something i am able to do?

SO all three lights came on and wouldn't go away.
Ran a scanner for code and got p0430.
Took it dealership for estimate or fix.
Go figure : code summary: Causes.
Reported fixes or Causes: for code p0430
- catalytic converter has failed.
- Air fuel ratio sensor
- Bank 2 cat converter
- Bank 2 (A/F) ratio sensor
- Oxygen 02 sensor
- downstream Oxygen 02 sensor
- Exhaust pipe
- Mass Air flow sensor
So I am waiting thinking ok let be one of the above causes or fixes that is cheap.
IS F (2008-2014) :: Headers And Long Term Reliability?
Headers will probably be the next mod that I do to my F, I have read a good bit about them on here, but no one really says anything about how they are doing long term ( any issues from heat on engine bay plastics after years of use) or how the coating holds up after years of use as track or DD or just anything else that seems to be an issue over time after being installed.

Do you think it would shorten the life of the hybrid battery if I make a habit of really trying to EV in the last mile of arriving home?
Tonight, I accelerated quite slow after the last stop to stay on battery, but I noticed the battery bars got down to 2.
Got to wondering, if I do this a lot, might it shorten the traction battery life such that it fails at 11 yrs, for example, instead of 14 years?
Ford Super Duty (1999-2016) :: Broken Exhaust Manifold Bolts - Long Term Fix?
I've got the dreaded broken exhaust manifold studs on my 2004 F250 V10. I don't drive it much (just 50,000 miles in 10 years) and confess I've ignored the hissing for quite a while. Is there really a permanent fix for these broken studs? Or should I expect to be replacing broken studs every 2 or 3 years?
If there is a permanent fix what is it? Special studs? Special manifold? I want to keep this truck a long time and don't want to be replacing these studs every few years.

View 6 RepliesLexus SC430 :: New Oxygen Sensor Reading Zero Voltage - Code P0430
Replaced my post cat drivers side O2 sensor tonight because I was getting zero voltage and a p0430 code. This is bank 2 sensor 1.
But I'm still reading zero voltage!! How could I still be getting zero voltage?? I checked the connections and they are firm. Checked every single fuse in car.
After my recent accident, the center console lights don't illuminate. My nav door doesn't close too. Could these all be related?? The connector for the O2 sensor is right next to the console, so maybe there is a loose connection or plug or perhaps a stray ground?? I do have wires all over the place in under the shifter bezel from aftermarket stuff..
Ford Super Duty (1999-2016) :: Long Term Negative Effects Of Heavy Condensation In Engine?
I only live 6 miles from work and I've been getting a lot of condensation gunk building up inside the filler cap and around the neck. Is there going to be any long term damage from this? Here is a picture of what I'm getting.
I know it's not coolant because I'm not loosing any and the oil on the dipstick is clean.
Since it got cold I've been taking another route to work that gets me up to 9 miles one way. Also, twice a week I take the long way home that has the engine running for a half hour but I'm still getting build up. In the winter I'm on call a lot and rarely go far from home so taking a two hour trip to really heat things up is probably not going to happen.
ETA. I change my oil every 3000 miles if that makes a difference.
