help with my 4 hour old 172 cup :(

[edd1982]

Just picked it up from garage and well chuffed for the first few miles

Whilst on the way home i noticed that when i accelerate hard from around 2000 revs and below the car seems to hesistate and theres a bit of a judder, then it picks up and away we go. Its fine if you floor it when the engine speed is already up at 3000 and above.

Its 2002 and done 53k if this helps. Car has 3 months warrenty from where i bought it, so it would be good if i have all my facts sorted when i call them tomorrow.

Cheers

got a decat?

 

[Harpham]

Mine also does this... Has a bit of a flat spot at around 2k revs aswell.

 

[edd1982]

No decat but it does have a big scorpion system on it. That will be coming off in a few days.

possibly lambda sensor. need to get it plugged in to see though

HT lead not connected properly
Misfire
Lambda like danny said too

Only problems i came across on other cars which caused that.


What the idle like?

 

[edd1982]

Idles fine, and everything else seems pretty good too, but i've not really had it long enough to inspect. Just wondered if this was a common fault?

 

[Craig Ed]

In all gears?

sounds management related, but could it be something daft like they've steam cleaned the bay, and gotten something wet? did you test drive it?

 

[sideways danny]

diagnostics test needed, but my money's still on lambda

i had this happen on mine but ive also had to replace the lamna sensor, try spraying all you electrics under the bonnet with wd40, if it is moisture this will help get rid of it.

 

[edd1982]

Yeah it happens in all gears.
Did replacing the lambda sensor sort it out Kevin?
Might suggest going back to the garage and getting it on a computer then.
Thanks for the help fellas

Injectors? could be that

 

[BROCKYS_172]

coilpack ??

 

[edd1982]

Think i need to get it on a computer to start with then, lots to think about there!

 

[edd1982]

Thanks for the help on this one guys.

Just to let you all know it turned out to be the plugs. Its sorted now and running fine...for now!
