Is this a sign of a bad opti?
I was just chating with one of my friends when my idle jump from normal idle to 1200rpms and idle normally again for another 30 seconds and do it again... So I go to take off and my car dies, WTF?
I hop on the freeway and go WOT and I get no missing or nothing, the car runs like a champ..... But at idle it just stumbles on its self or the rpms just jump around.
I
s this a sign of a bad opti or what?

My car does the same stuff, but it doesnt die, just almost dies. I have heard the opti may cuase this, 2 other board members had this prob and fixed it with an opti, so I am gonna replace my opti, coil, ICM, and secondary ignition and hope it goes away

Bad MAF perhaps.
