It is sometimes hard to start when cold.<br /> <br /> I adjusted the TPS. In researching the detonation sensor, it looks like it may be unplugged (see attached photo). Can anyone tell me where I should be looking for the female end of this plug? And/or what it might look like?<br /> <br /> ----<br /> &#039;&#039;&#039;Z_Karma:&#039;&#039;&#039; &lt;small&gt;(2021-06-02 20:37:26)&lt;/small&gt;<br /> <br /> iirc, the detonation sensor is a single wire that has a pinch&amp;pull white plastic shroud that acts as a strain relief and locking mechanism to keep the bare terminal in your photo secured into the sensor.<br /> <br /> I think the whole thing is covered by a large grey vinyl boot, like the oil pressure sender.</div>
