OK guys. I bought a 1995 ST recently. its always idled rough when warm, but when i first start it, it runs fine. well lately its gotten worse so i replaced the WHOLE dizzy w/ a known good one, plugs/wires(new toyoa), and throttle body. Helped for awhile then the issue returned. It got steadily worse till tonight where it completely died on me while driving. wouldnt start. no spark at all.. i swapped dizzys out again and it reverted back to the original random misfires.
Replaced:
So i checked the CEL codes and i pulled a code 14: Ignition Signal - no IGF signal to ECU 4 times in succesion. Not the ignitor, cant be since 2 had the same issue. i wiggled the wiring around and no changes. Resetting the ECU helps for about 20 min. Wiring or the ECU is the only other things i can think of unless there's something i missed. Any suggestions?

so check the commons first...
plugs gapped right timing right for dizzy this is a big one... CHECK ALL YOUR GROUNDS, CHECK ALL YOUR POWER FEEDS including fuses sounds like you have a bad connection somewhere... you wouldn't throw that code if it was an ecu issue... broken wire would give you more problems than random misfires... my money is on corroded ground... start at the dizzy and work your way back... ignitor has its own ground... check it... battery ground... whole deal... make sure your fuses don't have a partial burn This post has been edited by pittfirefighter: Jul 22, 2009 - 1:07 AM -------------------- Breaking Axles...

Weird thing is I'm a huge fan of "check your grounds first," yet i havent done so myself lol. I'll UPGRADE all my grounds tonight, and i know how/where to put some large cable lol. I'll update whether or not that helped the issue. -------------------- QUOTE "And, as always, your friendship, help, and dedication to the advancement of Texas Celica dominance is GREATLY appreciated.
