I am a U.S citizen living in Astana, Kazakhstan. When I first moved here in 2013, I bought a 2012 Lada Niva. It is such a fun car; hard to drive and no frills but a blast for sure.
For most of the last three years, the Niva has run beautifully, even in -40 degree weather, which we get sometimes. However recently, the Niva has started to have a strange quirk. I will be driving and press on the accelerator. The car will be moving and the accelerator will depress physically, but the engine will not respond. In fact, it will go down to idle speed. If I let up on the accelerator and depress again, it resets itself and it works fine until the next random episode.
This has just started since my last fill up. It has only happened maybe seven or eight times total. (some form of vapor lock?)
A little bit about this Russian built car: 1.8 liter 4 cylinder engine with fuel injection, all time 4 wheel drive with 4 high/4 low options as well as differential lock on the fly. For my needs, I almost always keep it on 4 high. The 4 high setting has not been changed since this issue began.
Hope you guys can help because my Russian is terrible. Thanks.
