Hi lads,

Just looking for some advice, I've noticed that my car has developed an annoying miss/hesitation when it warms up from around 1500-3000rpm when im driving around calmly. When im just resting my foot on the throttle keeping the car at the same speed, it starts missing/hesitating and the only way to stop it is by either pressing the throttle more, letting off or bringing it over 3000rpm.

I know it could be a 100 different things but I only have the car 6 months and I'm still learning about it lol. Any suggestions or ways to narrow down the issue would be great.

Thanks

Get it booked in at a reputable local garage, not worth causing unnecessary damage.

Could need the throttle bodies balancing(as a guess), but better to get it logged and resolved by specialist.

Whereabouts in the country are you? As there’s tuners dotted around who should be able to assist.

I've had similar before on three cars and it turned out to be throttle related. On a Peugeot, and later a Fiat, it was caused by a faulty throttle potentiometer module. On a Nissan Murano it turned out to be a broken accelerator pedal - there is a sensor in the pedal that does the fly by wire thing in reporting the throttle position to the Engine ECU. I fixed the Murano myself with a second hand pedal off eBay (was £80 I think) and had to purchase a couple of deep sockets. Simple bolt off, bolt on but takes a while as its a head in the footwell job, looking up and fiddly bits to remove - took me about 90 mins going slow and steady. Your problem might not be this of course but if it is - and Nissan use similar design/layout on the GT-R, it is a DIY job. Once fitted, I had to "program" the pedal to the car which basically meant a 20 min drive at different pedal loads to "calibrate" - got that from the workshop manual. Whatever, it did work.

Cheers lads, the car is parked up in the shed until the summer. I've plenty of parts to change on it so im going to try investigate it further then. I was just looking for a bit of imput as to what the potential problem was.
