Its a 97 ranger with a 5 speed. When I put it in gear sometimes the [engine](/topics-engine-ford/) will rev way up around 3500 and hang there until I come to a complete stop Mechanic's Assistant: How many miles are on the Ford? Have you noticed any fluid leaks lately? 79000 no Mechanic's Assistant: Are you fixing your Ranger yourself? What have you tried so far? I've cleaned the tps and mas and throttle body Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? Its throwing code p1121

Thank you for holding Chris, The common cause for the code P1121 to set on your 1997 Ranger is usually due to an inconsistent signal from the TP sensor to the PCM (computer) usually due to a failing TP sensor and or the connection to it. There is some testing you can do to determine if in fact the TO is the cause of the flaring Idle speed. I have enclosed the test steps for you in the link below. Let's run these test steps and see if this will help you get this resolved.
