XJR Jaguar rough running
Discussion
Hi,
I've got a 1995 Jag XXJR 300 (4 litre 6 cylinder supercharged) It's been sat for a couple of weeks (was running perfectly when I left it)and yesterday it started fine but would not rev over 2100 rpm, it would cough and stumble, this is both at rest and in gear. There are no fault lights on the dash. Called the AA, very nice man but his diagnostic didn't do much except show the same voltage at both lambda sensors - no fault codes came up. He's directed me to someone with more sophisticated diagnostic equipment, but I thought I'd try and find out what it might be before I spend the money. I'm a competent mechanic - if I can find out what bit's broke I can replace it myself.
Many thanks
Dave
