URGENT!!!!! Missfire

[w33 brl]

Clio Sport 172 suddenly just developed a majour misfire and seriously lacking in power, just put new spark plugs in it, made no difference what so ever, any suggestions or anyone know someone near by i can check coil packs ht leads? Thanks

Pre Cat Lambda?

Pre Cat Lambda?

got any other ideas? just so I can elimanate all other possibilities

 

[welshname]

coilpack?

Try swapping the Lambda sensors around, i.e. post - pre & pre - post & see if it sorts your problem out. If it does then just buy a new lambda for around £80-90ish (Bosh)
This happened on mine, was fine in the morning & fcuked in the afternoon. Turned out to be the manifold air pressure sensor that went, which made the car over fuel and drowned the pre cat in fuel & fcuked it!
APS was £70ish & is an easy fit once you have the old one out, the lambda sensors are even easier to change so long as you have a spanner =)

Might be wise to take it to a garage & get it on a diagnostic machine to save you from buying $hit you don't need.

Get it put on a test instead of just wanging parts on,more cost affective.

basically got the engine stripped as we speak! Very weak spark from the coil pack lead 2 only though, gettin 2 fault codes 0110 & 0136..................wtf is going on?!?!

 

[welshname]

Google the fault codes. They should be prefixed with a "P" aswell. P0110 from searching comes up with MAF sensor and Air Temperature Sensor.

P0136 points to Lambda sensor apparently.

changed the coilpack and plugs still not working ...ht leads orders pick them up on sunday so hope tht works

Map sensor fault? does it smoke / run rich!?

not smoke....engine codes that came up were p0110 and p0136

Do you know anyone with a 172 / 182 close by? may be worth swapping to try!

a was thinking that last night but a dont know anyone unfortunely if the ht leads dont work the aa's getting a fone call lol

Mine was leads.

Maybe injector?

Or Lambda, but does that just go like that, or does it screw your MPG first?

just changed the leads seemed abit better but still theres a lack of power anyone got ideas tht a could try tonight?

wot is the correct firing order?

 

[rob_sri]

jus change the lambda probe round like everyone is suggesting they can go at any point.. mine did and just started misfiring like a mothertrucker! you may be pleasantly suprised.. i was skeptical too about the lambda causing this much s**t but after pulling mine apart and changing that last it worked!

 

[rob_sri]

my lambda probe even rattled slightly when it came out!

MAP sensor, try it!
