Hiya, i'm new around here and joined for information and also advice into how i should go about dealing with my Z.

I bought this Z a few months back with a relatively unknown history, the only real info i had was that the engine was rebuilt in the last 5 years or so, has atleast a few minor mods (radiator, BOV, potentially turbo stuff?) and that the car ran decently well.

i've come to self diagnose that my knock sensor is knackered, my speed sensor either has a bad ground, worn out or needs a solder fix in the dash(0-5mph wiggle upon being stationary occasionally), and due to the 5~ years since an engine rebuild i think the timing belt + tensioners require doing just for peace of mind (the cars only done 4k miles since the rebuild)

i'm more electrically inclined than mechanically inclined so i wanted to ask for any reccomendations for shops that are familliar with z's to fix my knock sensor and change the belt + tensioners and to perhaps have a quick look over the general state of parts on the car. The only place i know of is PowerZed but its quite a trek (which i guess isn't the end of the world if y'all reccomend that as the place to go).

Welcome to the owners club and the top man for checking your Z is Jimmer.

You’ll likely find the cabling around the knock sensor rather than the sensor itself is faulty. If I remember correctly the stock knock sensor is only activate in a certain portion of the rev range, ironically not at the most dangerous point. Basically it’s pretty crude. I deleted mine and fitted a resistor to mimic its function, very common modification.
