Another rx im about to buy.....has a rough idle...the car lost a lot of Hp and the idle goes down to a wopping 400 rpm and i have to keep giving it gas to keep it alive....the owner tells me that he had it checked out and its the coil packs....it shady comments would help ....thanx

 

i dunno.. haltech has zero problem reccomending these as being some of the best on the market.. I've never seen a set go bad..
