waht plugs u using

[nareshseep]

ah feel he getting hesitation, use bkr5e-11 sparkplugs,

If you have a bad idle, and when you drive it bogs down at all rpms.
Then it could be coil packs, Replace coil packs

If you have a bad idle, and does not bog down at other rpms
Then it could be dirty maf, clean and test

If you have a bad idle, and does bog down (hesitate) between 1k -2k
Then it could be incorrect spark plugs, replace spark plugs

If you have a bad idle, and does bog down (hesitate) when you turn the steering at idle
Then it could be iac valve needs cleaning/ changing

i changed the coil packs same thing i'm using iridiums #7, i had on the bkre 5 before same thing,once i'm in traffic for about 10-15 mins i get this prob if i'm driving straight no probs

[nuffkuff]

iridiums cause more problems use the normal copper bk5res

[nuffkuff]

What kind of problems does the iridiums cause,because when i put them on FIRE down d road!!!!!

That heat range is incorrect for that engine either way.

You need bkr5e-11 or equivalent.
