Pinking

I'm not trying to go up at low revs/ labouring the engine. On the hill up to my house for example, I used to easily accelerate up in 4th gear. Not any more though, it starts pinking so I have to change down and rev it.

Just a thought, could be a electronics issue. Advance and retard are usually controlled via the ECU with signals from the crank sensor (there may be other input sensors as well on the Jimny).

I'd be interested to see if there are any codes stored in the ecu.

I have had bad experiences with Tescos normal unleaded in 2 modern fuel injected cars now, my Jimjam & my Mrs 325i E46 BMW.

Going on from what Mark rightly says about a hot spot, this could be created by it running lean. I'm thinking air flow meter reading more air than is going in or similar. What colour are the plugs. Do they show signs of lean running? This would explain the low idle speed & cutting out.

Google water injection see what you think of it

thanks.. I'll look over it again and check the plugs too.. I also tried to narrow down lean running by checking for air leaks in the intake side of the engine... thought the hub system was prime candidate as it did change when I removed and blocked the connection to the engine.. but not enough..

anyone got a code reader near DE6 ?

I live on a 1:6 hill so I need to get this sorted

I've booked it into my local garage which I've gone to for years. He's having a look at it next week. Will let you know if he finds anything.
