Repairing my old Ford Probe is even more fun than driving it

In the wake of nearly three months since the acquisition of my first hobby vehicle (or a weekend car, a project car, a restoration undertaking... whatever you like to call it), the fortunes of the 1994 Ford Probe appear markedly improved. Approaching its 30th anniversary (first registered May 8, 1994), this vehicular relic now boasts an idling rhythm close to perfection, a significantly smoother acceleration profile, and a near-complete restoration of its operational features. Nevertheless, a considerable distance remains to traverse before the car attains the condition to which I aspire. Let me tell you more about the recent developments. 

Upon my initial acquisition of the vehicle, it bore the peculiar distinction of a hybrid, though not in the contemporary sense involving the symbiosis of an internal combustion engine with an electric motor. Rather, its combustion engine had undergone modification to accommodate the consumption of liquefied petroleum gas (LPG), a prevalent practice in Bulgaria, where the conversion of petrol-powered vehicles to LPG propulsion holds sway. When executed adeptly, such an adaptation yields long-term fiscal benefits and incurs only a marginal decrease in engine power. Alas, such was not the fate befalling my Probe.

The 2.5-litre V6 powerplant, equipped with a multi-port injection system, proved suboptimal for integration with the antiquated LPG systems reliant upon a single fuel dispenser. Think of this system as an additional throttle body, tethered to the LPG infrastructure, bypassing the original petrol injectors whilst operating on this alternative fuel source. Such was the state of affairs with my car, compounded by a lazy installation marred by substandard sealants within the air intake and throttle body. The result? A vehicle showing uneven operation running on petrol, barely idling, and an almost complete inability to operate on LPG.

No drilled air intakes and pipes; new spark plugs and cables

Within a few minutes after purchasing the car, I took the decision to take off the LPG system, which aligned with my objective of reinstating the car to its factory condition as much as possible. One of my first goals after parking the
