k and n problems..

[marshy]

yesterday i fitted my k & n to the finesse..only problem being the intake pipe was too small..

so i swopped the intake pipe from my si to the finesse..i put the finesses maf back on..

now when i press accelerator in first gear the car struggles for a few secs and then kicks into life..

also when idling its very erratic...

any ideas??

Most likely an air leak after the MAF.

im glad you answered stu

after the maf?? near the cone end or throttle body end??

Anywhere after the MAF!

 

Changing the inlet tract, even the air filter, can lead to improper running but probably not to this level. This stinks of an air leak post MAF.

kk mate ill check it all n get back to ya!

[marshy]

i couldnt find no leaks... but i unplugged the maf and it seems to idle better... could it be cos i used a 1.8 maf holder thingy with a 1.6 maf??

Yes. You forgot to mention that! Edited December 6, 2010 by Stu

lol.. sorree!! whats my best solution??

it has the 1.6 maf on the 1.8 holder thingy and the 1.8 inlet tract..

put the 1.8 maf on?? but wouldnt that make it run rich etc??

[Stu]

The best solution is to put it all back to standard.

You need the 1.6 induction with a 1.6 MAF, and a 1.6 K&N

[bongo]

am i right in saying that you can swap the elements in the maf?
