So.. As many people here know, I have had misfire problems for a while... I have reason to believe that my spark plugs (Autolite DP's), arent working well in my zetec engine. So im planning on replaceing them with Motorcraft DP's... So today, I come up to a red light... im still rolling at about 5 miles per hour... and it turns green. so I put it into 2nd because im told as long as the car is rolling I can keep going from 2nd... So I put it into 2nd and let the clutch out I get my usual misfire.. but the engine is at a low rev.. I push the gas down and it clangs 2 or 3 times... it came from slightly to the right of where I was sitting... In the engine bay of corse... The thing about this, is that I have heard I think coming from the same spot a light tapping noise on occasion... Especially when the rev really drops (turn on the A/C and it gets a little louder).... The thing that is scareing me right now... is that its my Cat Converter...
Here is some MORE information prior to this event... Slightly earler I was sitting at a stop sign... It felt like the car was rumbleing arround more then usual... so I turn the CD player off, roll down my window and I notice my engine's idle is going nuts... its going up from idleing fine... to a rough idle and back up to fine.... I let it do this for a minute to see if it would fix itself... but it didnt. I tap the gas pedal, and the idle fixes. When I get to my destination and sit in a parking spot, I tryed to get it to do it, light taps of the gas pedal trying to put it back into the irregular paturn... But I cant do it. I go into the store, come back out and start to head home. I come up next to a REALLY nice Mitusbishi Eclipse TSI (looked like a 98). As Im coming up to the stop light as I push the brakes a little harder I notice my idle gets a little rougher... then I come to a complete stop, and my idle is down to crap again like the first time. Give the engine a little rev... everything is fine again. Then later I get the pinging noise... I have also noticed that my acceleration has been rougher lately... Any suggestions PLEASE would help so very much.
my CEL is NOT on.
