ONCE Again...POST # 5 ..yes, that is a very good possibility.
There can be, of course, other things to cause the same problem, but those are things like a bad ECU, MAF , etc...and I can not tell you that the plugs will definately solve the problem b/c my physic powers , along with my xray vision are not up to par since I got a dose of that Kriptonite...

What I am saying is PLAT DO NOT WORK WELL in you 104 engined car and before you go nutz with all the other possibles, put the CORRECT PLUGS in your car and save yourself a lot of trouble and $$$ trying to diagnose the problem with the incorrect plugs in it... if it still does it with the correct plugs, you have cheaply narrow it down..but there is a very good chance you will solve the problem..
