#138179, "Engine Misfiring Cannot Figure Out Why"


          

Hello,

It's been a loooong time since I've been an active member on this forum. It is good to be back however .

Anyways, to my issue... I have a non-turbo 98 GS with very little modifications done to it. One morning when I started it up it was running horribly, it sounded like a lawnmower. When I drove it around the block it lost so much power it almost stalled and during this period the CEL was flashing. The night before it was running fine, when I parked it all was well. I ran an OBII check and it came back with Random Misfires, Misfires on Cylinder 2 & 3, EVAP Leak Small & O2 Sensor. The leak and O2 codes I've had for years. What I've tried so far: I've replaced the Coil, Plugs & Wires and there was no change I have also looked high and low for vac leaks. I will be testing the voltage on the injectors tomorrow. My fuel pump and filter are relatively new.

I was wondering if anyone had suggestions to what this might be? My plugs were VERY fouled and I had replaced them only about 20K miles ago. Plugs on cylinder 2 & 3 were significantly more fouled than the other two. If anyone could point me in the right direction on how to proceed it would be appreciated. Thank you for your help.
