Because I have mechanical sympathy I haven't tried it with kick down as i know there is a fault. It is most noticeable when shifting into gear when the car is cold (raised rpm). When shifting from D to R it is noticeable too. If driven gently from standstill it won't bang, when switching from gas to petrol on the fly, the split second needed to switch makes it bang as engine loses power and then gets it back suddenly.
Previous owner did tell me this fault, although he failed to mention the rotten metal underneath 👀.
However, for the price I paid for the car (£1,000), with a working LPG system and relatively low mileage, I can't be too picky can I.
Good news is I've finished repairing the wheel well. (Yes I know the welding is nothing short of shockingly hideous, but, as aforementioned, I am no welder, just an Ape with a Mig.) 😂 And at least now my gas tank won't fall out whilst I'm driving.
Next on the list is getting the clocks out and getting them repaired. 😁
