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??
