so here it is very rough idles occasionally has stalled a few times when rpms drop to low all this at red lights or stop signs no CEL is showing all thats on the car is a K&N Short Ram Intake and a Custum Exhaust that i bought from Member SouthFL im a bit confused

 

hmmm sounds like ur coils are out or about to go out...what year and how many miles are on ur car?

 

2004 about 60000

 

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?

 

well this is my second rx8 and just bought it about 2 or 3 months ago so...... never lol

 

might be an noob question but how many coils??

 

yeah i honestly think its ur coils....heres a place that has em at a good price

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

 

20 minutes to change out coils? Damn dude you have some mad wrenchin' skills

 

^no bsin, its 4 little nuts and the connectors, its WAY easy

 

worth a try thanks for the help

 

chino look here, for spark plug info and how to do em yourself, its easier than it looks

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...
