I had a problem with car not starting - called RAC and they advised changing the distributor. Did this and car started but running on only 2 pistons. So changed spark plugs and HT leads - checked and cleaned all earth connections etc but still runs poorly on 2 or 3 pistons. Changed fuel injectors on pistons 1 and 4 slight improvement then back to 2 pistons !
Any ideas as my mechanic is now completely baffled ??
Thanks for getting back to me - there seems to be pulses and sparks on all four up to the fuel injection, and on to the spark plugs but the mechanic is checking the cylinders today via a compression test. I have also told him your suggestion re : throttle body so he will also test that for me and hopefully we'll reach a solution ! He can canabalise an old Nissan Micra to check the 'computer' as he puts it and the other parts so I don't spend too much !
