| I just thought I'd let you know about my throttle body problem. The accelerator was sticking in the morning. I would start up the Pilot and back it out without stepping on the gas. I'd shift into gear, step on the gas and the pedal would stick for an instant and then release, causing the car to surge foward...sticky throttle body. I've had it cleaned once and replaced twice. The mileage on the '04 is just under 20K. The tech said it's not an isolated incident and he's even had it happen to his Odyssey twice. SF Honda was excellent in handling the situation but I wanted to let everyone know about a potential problem. BTW, I also was told the throttle body is covered under the 7/70 program so I'm not worried about it not being covered if it happens again. |

I had my throttle body replaced under warranty (regular 3 year).
Is the 7/70 the emissions warranty (my regular 3 yr warranty is over)?
Thanks! |

| I believe the 7 year/ 70 or 100K (not sure) falls under the California emissions control warranty. All CA cars have it. I'm not sure about other states. |

Art,
what kind of gas do you use? |

Help me understand what was happening.
I'm assuming the '04 Pilot is the same as my '06 Pilot and is really "Throttle by wire."
With "throttle by wire", the gas pedal is really not physically connected to the throttle body as in older vehicles -- the throttle pedal operates a rheostat (variable resistor) and that ultimately sends an electrical signal to an electric motor on the throttle body to operate it.
So, logic tells me, if the throttle body itself were sticking, the gas pedal would return the full way, even though the throttle body didn't, because they aren't physically connected.
But, if the gas pedal, or the mechanical linkage, would stick, the rheostat signal would send a command to the throttle body to stay open -- so, ultimately, they both would be in the open position.
So, my question is: when it released, did you feel the gas pedal actually move upward? |

The throttle system of the 04' Pilot is not the same as the 06' Pilot.
The 04' does not have a "drive by wire" throttle system unlike the 06'. |

| David, I basically use Olympian regular. I know what they say regarding detergents in gas but I've never encountered this problem in any previous vehicle. I do understand the throttle body can have carbon or varnish type buildup but don't know if any detergent gasoline would have any positive results. I suppose it wouldn't hurt to try it. |

Art,
I've pretty much used Shell and, with the Shell branded credit card, get a 5% discount, which puts the net price in line with the independents. I think I have about 26k on my 2003 and, knock on wood, haven't had throttle body problems. I also pick up the 2-pack of Techron from Costco and will toss in a bottle once a year. |

Cleaning a throttle body on some vehicles is normal after high miles.
Also, some vehicles have throttle blades, in the throttle body, that have a special coating that can be removed by some solvents.
This special coating is supposed to delay the deposits forming on them.
So, I would check to make sure the solvent is safe for throttle bodies. |

| I understand, but the Pilot has less than 20k miles. I think 1 cleaning and 2 throttle bodies in 20k is excessive. |

| I also have 25k on my '03 and use premium gas all the time. Plus, the vehicle is garaged at night. So I don't know why the throttle is sticking again after it has been replaced with an improved version. |
