i replaced the CPS sensor, and air filter and it still hiccups pretty bad. but i notice it doesn't do it in the mornings since i put the new air filter in, but it does do it when it gets little warmer and its really weird. I don't think its PCM cause it would lope and idle like ****. Any suggestions? new sensors that aren't too expensive? THANK YOU.
Motorcraft CPS are the recommended brand. Parts house ones don't ply nice with these engines. If you didn't use a Motorcraft CPS, you might be having a problem with the one you installed.
