no throttle response

[coxxy]

i was just out driving normal, cruising bout 40mph with slight acceleration. when i come to put my foot down a bit the throttle didnt respond and it seemed like the engine was losing power then all ov a sudden it started to power up again. on the way home it has done it a couple of times now. Can anybody shed any light on this????

Clean the TB?
Check for airleaks? (though i assume this would be happening all the time)

Was it trying to cut out at all?

 

[coxxy]

i wouldnt say it was gonna cut out but there was just no power for a few seconds. The revs dropped then all ov a sudden it accelerated again

 

[coxxy]

im in wolverhampton too pedro and it couldnt av anything to do with the heavy rain cud it. could anything av got wet

 

[Pedro]

Doubt it unless youve left the engine bay open.

Im thinking TB now though. Im sure someone more experienced would confirm or not though.

 

[coxxy]

i cleaned the TB not so long back.

 

[Pedro]

Dodgy ICV? MAF?

LOL sorry. im not much use to you.

 

[coxxy]

just bin out and the engine management light is on

 

[Pedro]

Any other lights on with it?

 

[coxxy]

the service light has been on since ive had it. but it was on on its own

 

[coxxy]

just bin out in it and its doing it at about 3-3.5k revs

 

[Pedro]

Get it on the machines in Renault.

 

[coxxy]

just had it on a mates code reader and it came up with o2 sensor bank 1 p0310

 

[Fred@BTM]

was going to say, up stream lambda sensor

 

[coxxy]

is that the front 1 fred

 

[Fred@BTM]

yeah

 

[Christopher]

Yeah, it gets really coked up.

Get a mate with a blow torch to blast the worst of it off. If it's still no better, they're about £70.

 

[coxxy]

ive got a blowtorch

 

[daddycool]

isn't the lambda sensor fault code sometimes a bit of a red herring? if a car is over-fuelling, the lambda will get coked up and give an error. i'm looking into this as my zafira has been stuttering a bit. it's not getting upto temperature, so i need to replace the thermostat. as it's running colder than it should be, it's throwing more fuel into the mix, some of it isn't getting burnt and is killing the lambda sensor. just a thought, please prove me wrong though, i don't want to give out b****cks information, this is just what i've picked up from reading into my issue.

ist gettin up to temp but it does smell a bit rich
