Losing Power Whilst Idle at Traffic Lights

Have you tried cleaning the throttle body air intake? It can cure stalling problems or low idling. Can of cleaner costs about £5 from Halfrauds.

Take off the air filter and housing (just unscrew the 4 numbered screws) and you'll see a big hole. Spray the cleaner into that whilst revving the balls off the engine. You can also udjust the throttle cable from here.

Any joy?

How do you adjust the throttle cable?? Mine needs tightened abit.

from memory...

when you have taken the air filter housing off (again with the 4 numbered screws, this is slightly easier if you take the engine cover off as well) ) you will see the throttle cable.

lift the cable out of the housing and simply remove the spacer and put it back on to a groove closer to the end of the cable if it needs tightening or further away from the end of the cable if it needs loosening. if your unsure it will be pretty obvious when you do it.

the cable should just be under slight tension when at rest.

Right..

Yes the throttle been cleaned and re-checked this weekend to confirm no crap remainds in and around it.

To see if It was the dist/ cap I cleaned out the Cap and rotor arm and the car now starts and drives better than it has done since owning the car..

So I now need to order a new one as the current one is no good as it failed in the first place..

Too add to my misery.. I blew the baffle out of my exhaust erlier on this evening and the car sounds like it has mass amounts of air coming out of the back of it something like an aircraft. :-( - Stringy like material hanging out of my exhaust.

As this happened, I was driving in 3rd gear at approx 50 mph on a stretch of dual carriage way.. The car seemed to be abit sluggish in that it struggled to hit over 50 mph when changing gear and repeated itself at around 70mph.. Sluggish acceleration while the rev counter seemed to move quicker than the car did.

Anyway, the car is going into the garage on Friday for a check-up

P.S. Sorry to hear that orange

Ok mate heres some things to check and how to check them.

Im thinking the ignition system, with the exception of coil and dizzy cap should be okay, as any fault in other parts should stay no matter what revs.

The coil is just one wire 'coiled' with plastic casing as an insulator, if thats dead it should usually be spottable. A coil going bad is usually moisture getting in, through even tiny cracks, or losing voltage 'arcing' to car body.

Hence on the coil you should look for scoring, white marks, pitted plastic or any cracks, if none of that move on.

The dizzy cap - pop it off, squeeze it lightly and check for any cracks in the plastic, on the inside there are four metal contacts which should be clean, sometimes they get white powder on them. More importantly is the carbon rod, look at the centre on the inside, its like a black pencil rubber, it should be intact and smooth.

Air filter have a look should be clean, then check the thick ducting from the air filter to throttle body closely for cracks. this is true for every single vacuum hose you can see in the engine.

I would check all above, if the fault only occurs when the engine gets up to operating temperature, then is okay if you leave it twenty minutes or so and start it up no probs, then same again, then it suggests a G28 speed sensor, however this shows up on a fault reader usually.

I would do the basics, then think about buying a code reader, about 30 quid off a popular auction site.

Should be the other end of your ignition leads, one end is spark plug the other is inserted in the distribution cap.

Thanks for the detailed info. I will be replacing the Dist Cap and rotor arm.

Ive just taken the car into the garage this morning as it looks as if my clutch is slipping too.. i think i previously mentioned that in this thread.

P.S ive requested it in the main "wanted room"; but does anybody have a 1.4 Engine cover for sale? Mine never came with the cover when buying the car
