Hi guys - new to forum. 98 4WD with 3L. During idle, CE light flickers erratically but no code. Early on, racing the engine would stop the issue for a few minutes. Trouble began two days ago but is rapidly getting worse. Replaced Air filter and cleaned MAF with CRC MAF cleaner per directions on can but no improvement. Considering plugs/wires, vacuum leak, new MAF but hate to just swap out parts $$$$$.
Thoughts??
 
Thank you for assisting me. I have confirmed steady 1.2 VDC output from MAF sensor at idle, smooth output as engine RPMs go up/down. I'll replace IAC today/tomorrow and report.
Thanks again for your help,
Carolina
 
After weeks of maddening troubleshooting, I have taken it to my mechanics who cleared all error codes (MIL not illuminated) and report the issue no longer occurs. Enough to make a preacher cuss.

Many thanks for the kind assistance,

Carolina
