looks like you need new coils, you can get em for about 30$ a piece and do the job ur self, only 4 nuts and 4 connector that hold em down, should take about 20 minutes at the MAX....my cars doin the same thing, im gonna order some this friday...

when was the last time u changed em?

4 of them, they correspond the the amount of spark plugs you have (4) 2 trailing spark plugs and 2 leading spark plugs....you might wanna replace those while ur at it along with new spark plug wires

also look at post #202 for GREAT pricing on those spark plugs, amazon has for a lil over 15$ a piece...else where might charge for 80$ for all for, and stealerships are gonna wayyyyy over that and might wanna charge like 200$

take the intake airbox asnd piping to the TB off and the coils are right there 20 minutes including taking all that off...
