Technical Annoying me now...

[GhostWKD]

ok my car has started backfiring now

only thing i've done to the engine recently is taking (removed) a hot air feed to induction kit (for some reason had hot and cold air feeds), and now when i cruise at about 40mph in 5th it'll occasionally judder and backfire slightly (very muffled backfire) then pick up, other times its fine

anyone got any ideas what it could be? if its swapping bits over then its cool because i got my spare cinq for bit still

Dreaded word.....ECU.

GrpN Catback Exhaust system is here...just need to get the bleeder on now!!

 

[GhostWKD]

*dreads* i presume if i change the ecu i gotta change the master key? and if i gotta change the master key i gotta change all keys and if i change all keys i gotta change locks?

or is it a case of change ecu over with old cinq? (and/or use the old cinq's red key and reprogram current blue keys so locks still same etc?)

oh yeah and my induction kit is kinda (sorta, totally) very dirty B) could it be that possibly? (note: still makes the "whooosh" intake noise at bout 5k rpm upwards

Didn't it need hot and cold, hot for cold days?

Uno 1.0ie Start, oh yeah

You can just swap ECU's straight over - I'm doing it at the moment JUST MAKE SURE YOU DISSCONNECT THE IMMOBILISER FIRST! It's located directly underneath the steering colum, behind fuse box - 'bout the size of a cigarette packet - pull out wires... but obviously this = no immobiliser. But it's ok for cheaking to see if the ECU is at fault.
Hope this helps,

theres a sensor pipe that goes in where the normal air box would have been, when I put my induction filter on i was told to block this up or i'd have problems with the ECU being confused by it, could be sommuat like that?

other than that give the filter a damn good clean, most filters come with the cleaning sprays these days, halfrauds sell it if u haven't got any tho

ok pics of it before i removed the hot air feed:

removed the pipe from zorst manifold to the induction kit, other than that the engine bay is just as it is now

as far as im aware was working fine before removing the hot air feed, although was sometimes a bit dodgy on start (kinda not wanting to start, starting then just dying off even though i had foot on floor) then other times starting fine

ya know the injector light, when u start the car never ever give it any revs until that light has gone out, mess's it up so fiat told me, also press the clutch in, release then start it.

if you're induction kit is filthy then you reckon its possible its running too rich, therefore backfiring?

the warm air feed is to stop the throttle body icing up.. not needed


Cinq Sporting - and yes, its broom yellow!

 

[Bushboy]

put the hot feed back on lol and see what happenes. the original air box has one usualy. my K&N only has a cold feed tho and i have no probs. maybe u need a new air filter if its filthy lol... might not be gettingany air in

Do not put your foot anywhere near the throttle pedal when starting.

It don't need it

can you get cleaning kits for the k&n 57i kit? have looked and all sites show it being used on the replacement panel filters not the 57i's?

[Bushboy]

they are supposd to last around 1000000miles so they doint do cleaning stuff... howd urs get so dirty anyway? lol

also yeah, dont use the accelerator to start it... in my experience, it just makes it alot harder to start.

i thought they lasted that long but still needed cleaning? i've got cleaning stuff for my piper cross and they sell the universal cleaning stuff at halfrauds, maybe the hot air managed to penetrate throught the dirt but the cold air can't? if u've got the original air filter set up, stick that back on and see if you have any problems

 

[GhostWKD]

not got the original air filter stuff, got the cinq with the k&n

reading back my description was probably pretty inaccurate;

its more of a hiccup, loss of power for bout 1/2 second then it'll return all of a sudden(although sometimes a very muffled backfire which can hardly be heard, but can be felt.

oh well maybe time to get a gsr
