91 Octane In An R34 Gt-T

[stig mick]

Ok so I'm pretty sure I know the answer to this

I went and test drove a cheap r34 at a dealership today $15900 was the price but I though what the hey it might need a small amount of work but for the price I'd check it out

The car started up fine no smoke

Was idling at 2000rpm till it warmed up then settled down to 950rpm

Oil pressure and temperature were normal

BUT the check engine light did not turn off it stated on the entire test drive the car also didn't feel very like I expected I've owned and r33 before and the r33 felt like it had way more power

The dealer obviously tried to hide this by saying that when the car was picked up the driver filled the car with 91octane and that was the reason for the check engine light and lack of power

Could this be the case or is it more likely the engine is f**ked?

could certainly be the case. they are tuned for 95 octane fuel, so running them on a lower octane fuel will cause them to run like poo.

Yeah but had an s13 with a hole in the fuel tank I got it fixed and the stupid mechanic filled it up with 91 octane the car shook and spluttered an no check engine light

This car idled very very steady but just had no power and the check engine light worried me doesn't the light refer to an actually problem with the engine not the fuel supply?

[mad082]

if the knock sensors are registering a high amount of knock then it may come on. easiest thing to do would be to check the fault codes, or have them fill it with premium fuel and reset the ecu and see what that does. generally the CEL refers to an electrical issue (or damaged sensor). won't refer to the physical condition of the engine in 99% of cases

Well I told him to drain the fuel and refill it and call me so I'll do the reset on it when I check it out the car was stock standard so it should be an issue resetting it

i got some better advice, find another car there is to many of these car on the market to even think of buying one with problems is just crazy remember it's a buyers market.

goodluck with your car hunting.

15,990 for a GTT isn't cheap.. that's like standard price no?

From a dealership for a 2000 manual coupe turbo that's pretty cheap, went to another dealership and they wanted between 21000-25000 for their gt-t's and they had 7 of them

Yeah I ended up settling for a nice s2 r33 for $9500

It's stock as even has the airbox and SMIC so I'll save the excitement of owning an r34 for another 2-3years
