Bad idle

[david2807]

Hi guys, Basically the car was in garage for like a year, started it and drow it to different garage without problem... Then changed water pump and timing belt. Jumpstarted it and everything worked fine, but only problem is a bad idle.. It stays around 1k a bit less, thats normal, but it jumps up and down to keep it going, and the feels like the car is struggling to keep it up.. What could be the problem?
Thanks in advance!

Could be anything.

Air leak???.....

 

[STEVE.M]

Could be anything.

.

Very true, it could be a 2004 1.2, or 2007 1.4, or 2009 1.5 Dci.

 

[imprezaworks]

1.2

£5??

 

[STEVE.M]

1.2

£5??

1.1 1149cc 8v or 1.2 1149cc 16v?

 

[imprezaworks]

16v

 

[STEVE.M]

16v

Insurance would be cheaper for the 8v.
Guess we should ask him.

Drum roll.....

Yeah, thats what I thought, might be an air leak/vacuum leak.. need to check that first. could it be related to fuel as it smells like there is not a full combustion? Or it might be the air problem.. And its 1.4 16v 2003

Hurrah, thanks for the info.

Are you still using year old petrol?, and is the battery sufficiently charged to start without jump leads?

Is your next step getting an MOT?

Yeah, i can start it now without jump leads but battery is still not perfect... Passed my MOT yesterday, and yeah was running old petrol but yesterday put in some fresh one.. Cheers

As it has stood a while, take it for a good 40/50 mile drive to blow out the cobwebs before chasing after a minor fault that may disappear with use.
As the water pump was changed, recheck coolant level in the expansion tank.
K4J has hydraulic tappets, so no worries there regarding valve clearances.

Right, Yeah Thats what I thought, maybe need to drive around and just see what happens.. Yeah coolant level is okay... thanks for advice

Let us know how it goes.
One 50 mile drive is what I meant, not 10 5 mile stop start trips.

Yeah will do! Yeah I know what you mean, And probably try higher RPMs.. Might change the fuel filter as well, it's probably not changed since the build year, LOL.. Thanks for advice!!!

After driving around for a bit, haven't got a chance to go for a longer trip yet, but a it's getting better... just cleaned the throttle body and the RPM is 1k ish, and stays around there... Still struggles sometimes but getting better, so I believe a good drive will fix everything...
Just a quick question what cc fuel injectors does it have?

Id say failing coils

Id say failing coils

Couls this be a problem? It seems that only the mounting point is snapped... Already planning to get new one! Thanks
