hello , i have a 94 bronco 5.0 with mass air , and auto trans . when engine is started cold the idle goes right up to 1500 rpm and hangs there for 30 to 45 seconds or so. if i rev engine slightly t will drop down to 7 or 8 hundred , doesnt seem right that it jumps that fast as soon as it starts thanks for any info
My 89 bronco,auto also does this. no problem as it helps to keep from dying when colc. john
