I got this car about 6 months ago from a local classic dealer. Ht4100. 45k miles and looks very clean, was definitely babied by whoever had it before me. It ran great for a while but then I started to get a service soon light intermittently. Recently it has started having these “episodes”. It will be fine for a few days, and then (always while accelerating uphill) it will start to struggle and then eventually stall out, leaving me stranded for about 20 mins until it starts up again. Took it to a mechanic who literally told me he couldn’t find anything wrong with it!! So my dumb ass who decided to buy a classic as a daily driver is wondering if I’ll make it to work on time today. It also seems to revv itself up while idling sometimes and seems to run very high rpm when it starts up again after these episodes. Then goes back to normal after a few mins. My research has led to me believe this is either a fuel delivery issue or possibly a throttle body that needs to be cleaned? I would appreciate any answers from anyone so I hopefully don’t spend hundreds maybe thousands on part replacements I don’t need if this is as simple as taking something out and cleaning it. Thanks in advance
