Did this video help you?

Tom P: great video thanks :)

David Kinsey: Great video and thanks for posting.  This seems to be the most often noted problem when the "Engine Failsafe Mode" light comes on in a Ford truck.  It happened to me on my 2006 Expedition this morning so I will give this a shot and also used a bottle of Techron cleaner.  This seems to be the air source, however, not the mixed fuel source as it would be with a carburetor.  Any other tips or things to do at the same time?  Air filter was changed a few months ago but I will check it, of course.

Tony Runyon: Will a dirty throttle body make a car or boat pop through the intake under load? I've done all the obvious drained the gas replaced all filters cap rotor plugs checked the timing cleaned the air filter. Any suggestions ? Indmar monsoon marine 350 injected 

Osigwe Stella: it also shows ENGINE FAIL SAFE MODE before it stops.

Osigwe Stella: I bought a 2005 freestyle ford model and have not been able to enjoy this unique car due to these following problem. (1). when I go above 50 to 60MPH, it will lose power completely, the wrench and traction light goes of and I have to restart the car before it could get going (2). but does not cover up to 20KM before it stop again but when am on below 40MPH it would not stop (3) and sometimes it feels like the car is heavy. please tell me what problem is this and what can be done. Accept my warm regards. Stella from Nigeria

RAFTERMANCOLO: Sadly my truck is at Christian Brothers right now for just this issue. Thanks for posting the video as it did provide a clear understanding of the total issue.
I'll also say this is the 2nd time I've used Christian Brothers, and so far, I'm VERY pleased with their work and especially their pricing..!

Uptown Photography: My mom's 2.8L 1989 Buick Regal (only has 50K miles on it) was surging when slowing down to stop and would stall. The Idle Air Control Motor was replaced, but she's still not running well. It doesn't surge as much but still stalls and hard to start at times now. A new problem also seems to be the car will run without giving it gas, meaning I was doing 47 MPH without giving the car gas on the highway the other day. Never did that before..Do you think it's a TPS (Throttle Position Sensor) or what else would you suspect. Thanks and great video...


roque arellano: What solution did you used to clean that throttle body ? Cleaning that crap, Could it the answers to my slight idle problem ?

sixstrangtommy: Question: If the throttle body is dirty will it affect the gas mileage too?? On a 05 qx56 can I clean it myself without a shop charging me hundreds??

Mateo Sepulveda: i found that battery problem out the hard way, when i got my moms 2002 subaru impreza wagon 

Kar Ser: I got a Hitachi TB for $60 online..installing is the easy part..its the Idle re-learn that's going to set me back $160.00. It seems ONLY Nissan has this scan software..tried everyone in my hood to see if I can lower the Nissan price..but it looks like i'll have NO choice but to deal with Nissan (again).

Kar Ser: one other thought..I wouldn't mind going to take the car for second opinion (with old TB) but at $160 a pop, that's not cheap..i'm still trying to find a regular mechanic who has the Nissan software to do the idle re-learn, some garage in my area must have this software other than Nissan...cause I know Nissan sells it as well.

Kar Ser: going back to a dealer with old TB would mean that IF it fails second time, I would be forking over $$ for 3 tests in total..i found the new TB cheap enough its a Hitachi brand and have confirmed it will fit my car. So I think putting new one on, and going back to dealer is most prudent step..i am assuming by the last remark you made on last response, you agree as well. Incidently, do you think dealer would charge me full price upon return for the second re-test ?

Kar Ser: would you believe they wanted to charge me $1,200 parts and labour to replace the TB!! I found the tb new (oem) for $60.00 + Ship online. So im not sure I follow you on a couple of the are suggesting i replace the part anyway right ? And, IYO do I need to get the idle re-learn done on the new TB ? Lastly, do you forsee any issues with me trying to install the new TB? Obviously, there will be no cleaning involved this time.

Kar Ser: i'm sorry to hear that..hope you are doing better.
Well, I don't think it was that simple as a vacuum leak.. I took it to Nissan, they are saying that while I cleaned the TB I removed the thin coating/film in and around the butterfly and therefore it failed the idle re-learn, they thankfully reduced their fee from $165 to half, because it failed the test. I used TB spray to cleaned it, AFTER I disconnected everything. They advised I get a new TB so I luckily found an oem online for really decent price (new), so my question now is, will I still need to pay again for the idle re-learn, even with a new TB ?

Kar Ser: Hi can you please advise..i followed precise instructions as suggested for my 07 NissanAltima. There was a lot of dirt in the throttle body, I disconnected battery prior to pulling it out completley, did everything as suggested...BUT I now have a HIGHER RPM than before I took the throttle out...I cant drive the car now because of the high rpm..I pulled and put it back exactly as I should, all wires and hoses connected to their rightful place..what could have caused a worsening of the rpm, I don't understand ??

TheEliminator: So it's safe to spray the throttle while the truck is running?

BlackMafioso: Omg TY I'll try it on my next day off I took my car to a mechanic and this fool tried to tell me I have a blown head gasket and wanted $1500 .after that I had 0 trust in the guy.  My head gasket is perfectly fine, I guess because I'm young he tried to take advantage of me but I wasn't falling for it, I had no milky oil, no overheating. no coolant loss,no white smoke, no oil in my coolant "which he told me I did" but when I checked it it was still pretty clean. Also I had a coolant flush 2 weeks in advance I'm pretty sure I would of found out then, But my car does everything in the description I guess that's why it never happens on the highway, getting more air I guess. thx for the video and maybe I wont have to pay another mechanic $100 to be lied to.

Jeremy Boney: I am going to try this on my subaru impreza 06 rs I am having idle issues and am starting with the cheapest first. Anyone have a great safe throttle body cleaner brand for my unusual boxer aluminum engine?
