Slow pickup between 2-4000 rpm 6 Years, 4 Months ago Karma: 30
Hi Guys .. after taking my MR2 for a spin to work today, I've found that it's hesitating between 2000 and 4000 rpm approx. I have a boost controller on it (Blitz Twin SBC ) and I've tweeked that so it's not so bad now. I've noticed the odd backfire when letting off the power and that the idle is running slightly high ... about 950 rpm

Any ideas guys? Timing or a coil pack?
All assistance greatly appreciated ... beer vouchers provided to the winner

I think that I may have over complicated the matter :-p
Car was meant to be serviced when I bought it
Air filter filthy and plugs don't look the best either

@Spla300 ... I think the timing needs to be done also, maybe the bad plugs would have knocked it out of whack??
