Talk about a scare...


Recommended Posts

I decided to drive over to my wife's place of work to enjoy lunch together, yup I'm a big softy. Anyway as I pull into a parking spot and start applying my brakes, the trust doesn't slow very quickly. As in I almost hit the car in front of me, so I jam the brakes and I stopped. I look at the dash real quick, nothing out of the ordinary...except the tach shows ~1200-1500 rpm. I gently release brake and sure enough I begin to roll again with a purpose. Engine is definitely not going back down to idle. Well I shift to Park and the tach jumps up to ~2000 rpm and now I can actually hear the engine speeding up. I had the radio on so I didn't hear the engine at the lower speed. Just as quick as it jumps up it went right back down to idle and all was well. No lights, no dings, no messages, no other gauges reading anything out of the ordinary.

So once lunch was done I, carefully, drive back to my work and of course....nothing....all is as it should be, thankfully. Now I've cleaned my throttle plate before and didn't have a problem and I only peaked at it this weekend while I was servicing my air filter (K&N), but I drove it around all day Sunday and yesterday with no problems....odd! So I guess I'll keep tabs on it and see what comes of this. I guess after 6 years and 95k miles I can start expecting some "new" quirks to my "old" truck.

Well if you're still reading, thank you for your time. I appreciate any comments or suggestions.

LOL! I wish. Nope no Toyota today. It was a Jeep I tried to hit and a couple of other trucks. Parking lot was mostly empty since most everyone left for lunch. Hasn't acted up since so hopefully a fluke.

I know if you start the car with the electronic throttle disconnected (a small metal box on driver's side firewall under the hood) it will idle way fast. Might be worth making sure that wire is running with no rubbing or shorting and that the connectors are all tight.

I'll take a look see into that. Thanks for the idea.

Has it been raining a lot lately? My old Montana van used to do this if it had been raining a lot. Something to do with a sensor that was not working right. Not 100% sure what sensor it was, we traded it in.

feed it a honda, its just hungry

 

It has been a while since I've been able to load the truck up and truly work it. I gave it a teaser this weekend with my travel trailer around the neighborhood so the truck might just be egging me on to load her up...still have those blocks you were lugging around awhile back...lol

I did take a peek at that. There isn't anything obviously wrong (loose, busted, unplugged, etc), but I didn't want to start disconnecting connectors. With my fat fingers I'd probably end up breaking more just trying to find anything broke. It still hasn't acted up since so I'm "hopeful" it was a freak of nature, need to eat a Honda (thanks Grape), one time thing.

you commented that you messed with both the air filter and peaked at the throttle body - I would bet on the intake tract not being reassembled correctly or a vacuum line is knocked loose - it sounds like the motor is getting unmetered air (air is getting sucked in from somewhere after the MAF sensor.
