    I can't get my engine to idle down. I have replaced the IAC valve but that did not solve my problem. What else could be causing my problem?

    have replaced computer aic maf or map whichever tps switch checked hoses ,just about everything i can think of. Idles at about 2100 rpm and now its started sputtering when so called idling. mash the gas and it goes just fine. but will not idle properly. any suggestion would be worth a million and a half.

    Engine infrequently races in idle, sometimes up to 3,000 rpm. So many Ford Ranger owners complain of this exact issue, Ford should have done a recall repair for the problem. Instead, every Ford mechanic I've talked to (several) seems clueless ... as if it's a rare isolated issue.

    It started when I was driving on the freeway, first, it feels that it lose power, but kept running, drives really slowly, it goes only in first gear at 15 miles, like when you carry a lot of weight, and uphill can not drive.
