Stilo fault codes 1684 1687 1220

You replaced the acceleration throttle body and you might get your money back???
Here in Greece i paid for it, the problem didn't solve and spend a whole lot more to find that 3 out of 6 cables of the throttle body where turned black!!!
Solved it after soldering them...

Hi all - Stilo has another trip on the back of a recovery truck!! Fault code 0300 0304 which I think is misfire on cylinder 4 - bearing in mind we only got the car back on thursday having had new ecu and throttle body - could the misfire be related - thanks in advance for any comments/thoughts?

you got right plugs fitted?

What do you reccomend?

Hi all - changed one coil last night and think one more has gone - is it common for two to go together? Some white dusting around those that have gone - is that a sign? Ta

Last time i've lost 2 at the same time... The car was trebling like hell but at least i've enjoyed the Subaru WRX sound of it... For a while fo course!

A coil breaks down because it can't stand any more, it's at the end of its tether and it won't take no more. As you had fault code P0300 multilple misfire and P0304 cylinder 4 misfire then have you followed T1's advice and checked your plugs? Bad plugs or wrong gapped plugs put huge electrical loads on the coils insulation and electricity likes to take the easy way out

Have put new plugs in and 4 new coils - seems to run fine, but on idle is only about 650 and a little uneven - did a throttle relearn - no change - also when put foot on throttle pedal - it seems to increase, then step up in increments (ie can't hold it at a steady rev) - any suggestions? Ta
