Yup. Friday afternoon, a mate picks my car up from the tuners after having the belts tightened and the tuned slightly modified. Ask's me if he can take it for a spin round the block, i say yes. I get to his place after work to pick up the car...he tells me it is sounding weird, i start the car...it sounds like a WRX , i think either coilpack or sparkplug...ring a mate, and he sort of confirms it, and give me some soultions to fix it, they dont work.
Luckily my mate has a garage out the back, so i drive the car in, and pull out the coils and plugs. Coils look okay, plugs....are black and 1 of the 6 was moist. I swap the plugs around, aswell as the coils, put it back together...still the same - now i think about it, of course it would. So i leave it for the night.
Come back on Saturday with the stock coils and plugs that were in the car before. Change plugs first, start car...runs fine, rev it a bit, still runs fine. So i take the car home, all fine, take it for a spin once i get home, it stalls randomly 1-2 times, but other then that runs fine.
Take it to work today, runs fine, on way back from work, the car starts loosing power, dropping revs, and jerking, aswell as stalling at the lights 2-3 times. So i take it back to my mates place, where it is now until Tuesday, when i can take it back to the tuner.
My guess is either wrong plugs - put in Iriway7 first, then swapped back to PFR5G11
or
A Bad tune - Too Rich, not good with this heat.
or
Ignitors may be playing up in the heat.
It had been running fine until Friday afternoon, had gone about 1000km before then.
