Warning heat light????

[Ste C]

Hi Si... I guess your not to keen on Hurley`s either, how come?

[Steve Burnett]

You\'ll find out. There is a rather large post on Mr Si\'s dislike to that particular company. With good reason too.

I\'ll let Si post the details on this one.

[J.j.]

Just a thought, if it does turn out to be the CAT, then instead of buying a brand new one, get a DeCAT(200 something?).  When it comes to MOT time, you can always borrow a CAT for the test.

Is there anything special about decating an FD3 ??
When I decatted the FTO it only cost 50 quid.

I took the car out to the garage today so that I could use the pit and remove the back box. After looking into the CAT everythings seems fine. Is the sensors for the cat on the top? Also do you think a lack of a good drive might have caused the stuttering light. To soon to tell but the lights not been back on since I gave it a good blast on the road.

[scooby_si]

Ref decat personally wouldn\'t do it without power FC or similar mapable ECU. May survive but generally i\'ve heard people say as a guide anything more than 2 mods then get ECU done. Basically if you aint a gambler have ECU high on the wish list IMO.......http://www.smileycentral.com/?partner=ZSzeb008_ZNxdm46052GB\' target=\'_blank\'>http://smileys.smileycentral.com/cat/17/17_1_10.gif\' border=0> lol

Light still flickers, the engine note alters when the light comes on. No idea what the hells going on but I am becoming a bit ****ed off as its one thing after another at the moment.

Not sure.... if you are detecting a change in engine note when the light flickers, could well be a defective air pump, if you have your cat in place [still not sure if you have or not:confused: ] As stated before causes for the light comming on :
 
1 Blocked cat

2 Defective air pump

3 sensor earthing out

4 Knock reading [if you have a PFC

Prob. missed a couple, but they seem to be the main causes.

Hope this helps:wave

[Steve Burnett]

Thanks John,
Yes the car does have a CAT, I removed the back box on Friday and had a look at the CAT, all looked fine.
Not sure about a sensor or the air pump but I\'ll try and find out.

My next question then is, how do I find out if the sensor or the air pump are not working?

p.s. no PFC fitted so knock reading is out.

[John Yorke]

Air pump has a clutch when you rev it manualy [looking into the engine bay] you should see it engage,if it does not, that would be your problem, the sensor is situated to the side of the cat, make sure the cable is connected correctly, that I\'m afraid is the extent of my knowledge, I ditched both the cat and the air pump before they gave me problems [think of all that weight I got rid of:D ]

[Steve Burnett]

I was under the bonet today and the I heard a metal ticking (something like that) coming from around the air pump, as I reved the car it would tick twice. I disconected the electrical lead going to the air pump and hoped that this would stop the heat light coming on. Unfortunatly not : reallymad
The engine at idle was then changing note as if the car was serching for the right revs to sit at. The rpms also dropped down to about 400. This problem is really beging to get me well :reallymad

[Rich Cheung]

What is the job of the air pump ?
What are the benefits of disconnecting it ? Is that easy to do ?
