Can you give me more detail on what exactly is going on? Did you check for codes in the computer with a scan tool? How many miles are on the vehicle? Any service history recently leading up to this current problem?

Can you get me the specific code numbers that were set in the vehicle previously besides the lean condition code that should be a P0171 I need the other malfunction code numbers set previously and if it's settings again.

Do you have any ideas In stead of questions?
Toyota Mechanic: Skyvisions, ASE Certified Technician replied 1 year ago

Based on your last reply it seems as though you're just interested in a cookie-cutter fix all answer. There are none, in order to provide you with a quality answer that will get you on the road again it requires lots of questions to get to a reasonable conclusion. At this point it doesn't seem like that is something your in line for I will opt out so you can work with another expert.

Sorry went on vacation and was out of touch with email and the only reason I am trying this again is a had a buddy with same nick name back in high school .
Here is the low down on my issuesI had a lean cylinder on 2 and 4 and one time a vvt code but I did not get the code numberI have a 2002 Toyota sienna ce , when driving on the highway with cruise control on or off the engine acts like it stalls but after few seconds it of losing speed it picks back up again it will do this about every 15 seconds to one minute . I have changed the idle air control motor , tps , changed all coils and inspected and cleaned the vvt solenoid . The motor was rebuilt mechanically because of a spun rod bearing and has about 10k miles and I had the transmission gone through at the same time . I had a bad vibration while going into overdrive and I took it back to transmission place and they changed fluid and put some kind of special additive in transmission fluid and it fixed the vibration issue I brought it back when this issue started and they said there was nothing wrong with transmission that they thought it was in computer or ignition system . The strange part is I can pull over and turn off engine wait a few minutes and restart and it will drive fine and when it has the issue it tends to idle a little rough . I have it back on analyzer several times since I changed the tps and idle air control motor and have no codes come up since . I have read a bunch of stuff on line about them speeding up on there own but not what seems to be a loss of power I do not think it is fuel because once you get it over 85 mph when it doing it the problem goes away . Have you ever seen this issue I keep replacing parts that seems to be bad but does not seem to fix the intermittent issue .I was thinking about bringing to to dealership to see if the ecm could be reprogrammed It has not be to dealer since 2007 when I bought it . Thanks For listening to my issues maybe you can help . Thanks Boyd
Toyota Mechanic: Chris (aka-Moose), Auto Technician replied 1 year ago

When driving and you start losing speed and power, does the engine misfire or just bog down or act like the throttle is no longer responding?

Ask Your Own Toyota Question
Customer reply replied 1 year ago
No bog down almost like you lift off the pedal and and depress it again over and over again and it does it with cruise control on and does not set. Any codes in computer
Customer reply replied 1 year ago
if you apply more pedal it picks right back up again like if had let your foot off the pedal
Toyota Mechanic: Chris (aka-Moose), Auto Technician replied 1 year ago

I final got codes what do you think coils were all replaced 1 year ago almost to day nowPO 300 random multiple cylinder misfire is detected
PO 302 cylinder two misfire detected
PO 304 cylinder for misfire detected
PO 306 cylinder six misfire detected
PO 171 fuel system to lean bank one
PO 174 fuel system to lean bank to PO 770 shift solenoid E FAULT
P1354 VVT SYSTEM FAULT BANK 2
Toyota Mechanic: Chris (aka-Moose), Auto Technician replied 1 year ago

The codes point most to a cam timing concern on bank 2 which is effecting the compression and causing these misfires your getting which all happen to be on bank 2. The lean codes can be caused from the cam timing and misfire concerns so that has to be addressed if even needed after getting the VVT bank 2 working right. Do you need the diag steps on 1354?
