Surge at highway speed.

[Limited '95]

My '95 Limited has begun to surge at highway speeds, most notably with the cruise control on. I've sprayed a can of throttle body clreaner through it, cleaned the MAF, cleaned the K&N, being ever so careful not to over oil it, and checked the PCV valve. It's almost as if I have an injector leaking causing it to surge.

It's hard to believe that twenty-five years ago I was a Ford certified technician. This 'new' stuff is really frustrating.

Any thoughts???

I had the same prob a few months ago and I change the tps sensor ...and no more prob since...$50 ! But it was worth it !

good luck

oh and one more thing you have to check is your speed sensor...it regulates your cruise control...I have the same prob...it does it only when i`m using the speed control..but i`mo not changing it for now..I believe it located on the trans.
