vroomba Posted September 18, 2016 Report Share Posted September 18, 2016 Keep the car running smoothly and potentially get back some lost performance by cleaning the Throttle Body and Mass Air Flow sensor The throttle body controls air flow into the engine and will open and close when you press or release the accelerator pedal. The MAF or Mass Air Flow sensor is a device that measures the density of the air coming into the engine from the air intake. This data is used by the car’s computer to help correctly control engine fuelling. Over time these will get dirty so if you think your car is running a bit sluggish or worse stalling or in limp mode then cleaning them may cure this problem.

Dodgster Posted August 17, 2019 Report Share Posted August 17, 2019 Hi , i desperately need need some help. I've just cleaned the throttle body as per the instructions and now my car is running rough, kangaroo hopping and cutting out! I'd appreciate any help possible as before I did this it was running supremely smooth and I only attempted this as its done 93K and I hadn't a clue as to if it had been cleaned before. Now when I start it the car cuts out. Help! Link to comment Share on other sites More sharing options...
Scubaregs Posted August 17, 2019 Report Share Posted August 17, 2019 Have you made sure everything is connected back up? Vacuum leak? Did you clean the MAF? Link to comment Share on other sites More sharing options...
Dodgster Posted August 17, 2019 Report Share Posted August 17, 2019 When I was cleaning the throttle body the hose to the air intake (leading to the air filter) became dislodged however I refitted it to no vacuum leak. I didn't clean the maf as I didn't have the correct torx adapter (the ones on my car had a little indentation in the middle so my torx wouldn't sit in) i'm kicking myself as I've had the car for 1.5 months and it was running smoothly before!

Scubaregs Posted August 17, 2019 Report Share Posted August 17, 2019 Any codes showing? Could try disconnecting the battery for 5 mins as a reset. Link to comment Share on other sites More sharing options...
Dodgster Posted August 17, 2019 Report Share Posted August 17, 2019 I don't have a code reader. I tried the wait for a minute reset which didn't work so I think I've got nothing to lose if I disconnect the battery. hopefully that will reset it.

Dodgster Posted August 17, 2019 Report Share Posted August 17, 2019 I've just disconnected the batter for 5 minutes. No joy. Now I start the car, it turns over then cuts out! Not sure what to do now. Link to comment Share on other sites More sharing options...
Scubaregs Posted August 17, 2019 Report Share Posted August 17, 2019 AA/RAC? Have a cuppa, go back out and methodically go back over everything you did. Look around the area, perhaps you have dislodged something nearby whilst you were working on the car. Link to comment Share on other sites More sharing options...
Dodgster Posted August 17, 2019 Report Share Posted August 17, 2019 I will check but I don't think so. I may need to call the rac. Would you suggest I tell them I've cleaned the throttle body or play dumb? Link to comment Share on other sites More sharing options...
Scubaregs Posted August 17, 2019 Report Share Posted August 17, 2019 I take it you have home start? Might as well be up front, gives them a reference point and don't think it will matter tbh. Link to comment Share on other sites More sharing options...
Dodgster Posted August 17, 2019 Report Share Posted August 17, 2019 Yes I have home start. I'll give them a call. Thanks for all your help my friend. i was panicking when I've been paying that subscription for years snd never use them! Link to comment Share on other sites More sharing options...

Dodgster Posted August 17, 2019 Report Share Posted August 17, 2019 RAC on the way. Incidentally since I cleaned the throttle body I've come across a raft of people on ten 'net who have had the same issues as I've had after cleaning it. i think in the future I'm going to be reactive as opposed to pro active when it comes to the internal workings of the engine!

PhilTUK Posted August 17, 2019 Report Share Posted August 17, 2019 Are you sure you have both of the vacuum pipes pushed back in? After cleaning mine it was running as lumpy as erm a camel(?) I found a vacuum hose had become detached, there were 2 similar hoses, one for each bank. Re-fitting the pipe made everything just fine. I hope you find a fix soon.

Hughsehhh Posted October 11, 2019 Report Share Posted October 11, 2019 Anyone else have experience of cleaning the throttle body and want to give feedback, good or bad? I guess it's one of those where all being well, people do it and it works fine so they don't comment, whereas those that do have issues raise it on forums such as these. I was due to do mine this weekend, but a little reluctant now. Link to comment Share on other sites More sharing options...

I was due to do mine this weekend, but a little reluctant now. I did mine a couple of weeks ago as it had to come off to access the PS pump. I was a bit foxed when I found a vacuum pipe at each side, but turns out this is only for Tip cars. There is a nut holding the TB to the engine which was tricky to remove as access under the TB was tight. Cleaning was straightforward with a bit of carb cleaner, but there was a fair bit of oil in the black tube leading to the inlets, so I think my AOS maybe past it's best, but I didn't want to get further involved and left it for another day. Re-assembled and took it for a good thrash and all worked fine. Haven't touched the MAF as it seems to be working fine. Maybe when I change the AOS I'll give it a clean. I only did mine as I had to take it off anyway. Not sure I'd bother taking it out just to clean it if the car is otherwise running well. Always the risk you'll disturb of break something as chap above did. Link to comment Share on other sites More sharing options...

Always the risk you'll disturb of break something as chap above did. That's useful info. I have the 2.5, cable controlled throttle, but otherwise the process will be the same. About 6 months ago when stopped at the lights, the revs really hunted and woudnt idle. It's only happened the once in 10k miles, so I expect giving it a bit of a boot has cleared things. I also cleaned the maf at the time, which is very easy. Maybe I'll leave it then Link to comment Share on other sites More sharing options...
