ok thanks
i'm just worried that this has anything to do with me putting 87 in the last tank

 

Bro, putting 87 in one time isn't going to f00k up your engine. Don't do it on a regular basis, but once ain't gonna hurt you. Now, change your plugs, coils, and wires and see if that helps.

 

^ yea thx... they are coming on tuesday

 

guys... i changed out the coils, plugs and wires today, and uh... the rattling on high revs are gone, but the poor idling and shaking is still there when idle. i reset the ecu already (reset + turn ignition twice & brake pedals 20 times) but nothing seems to work, what do you think might be the problem?

 

hm... P0336 engine light came on today, anybody knows if there's anything doing with the issues I'm having, i'm researching abt the code.
THanks

 

update: got new engine mounts from the dealer, found out it's still under warrenty. problem kinda fixed, car's still idlling weird though, it was clean 1k before, now it drops to 700-800 rpm
