[QUOTE="jpjeep26uk, post: 436644, member: 20690"] Flyer that's really helpful guidance. I'll do this on Saturday and see how far I get. I'm beginning to think it's pure coincidence that it showed up the same day as a belt change. It just seemed really odd after 2000 spotless miles around the UK in 3 months - one bit of which was done at a steady 56,mph non-stop for 5 hours- not a peep. Work so far this week to find the culprit- [LIST=1] [*]Pulled the ignition pack off and apart from 30 years of dust it came up clean after a good brass brush with contact cleaner (new one coming this weekend), [*]Replaced the spark pugs and to torque amount, [*]Pulled the dist cap and it did have some kind of light oily deposit in it so I cleaned that too and the rotor (New ones coming Saturday) [*]Took off the PCV valves and soaked them in Carb Cleaner and cleaned the metal one with a gentle brass brush (new front metal one coming on Saturday - I can't locate a rear plastic cylinder one for love nor money!) [*]Replaced the fuel filter as well. [/LIST] After all that work as well as cleaning up the TBI again, the pic above is the result along with backfiring and a terrible idle so I'll fit all the new bits and then follow what you say above to see what's up. Again - thanks for the guidance. [/QUOTE]
