Maybe a bit more info, whats it doing, or not doing?
The description is a bit vague, it could be a number of things, take it to your mechanic, see what he says...
Are there any modifications you can tell, that have been done to the car?
Did you buy it from grandpa, or some fully sik young fella?
Has is boiled/got hot recently?
Does it misfire?
im just looking to find out who to bring it too, not how to fix it myself. will a normal mechanic do? or some one else, more specialist?
some sort of different exchaust, because its loader. bought from car yard and has been modded with it being lowered. k&n air filter. not boiled recently, not sure bout misfiring.
mate take it to a workshop that does their own dyno tuning.
They'll have all the gear to check and/or tune if required
Most regular workshops will have the gear to check the engine management system for problems, but usually won't have the gear to re-calibrate the memcal. Need the likes of a dyno tune workshop
