330i. E30 Touring.
Well after a little bit more driving with some fresh fuel it is running a lot better, no stuttering or flashing eml lamps. However it does seem to have a slight hesitation above 3.5-4k rpm and the power drops off a little, doesn't do it all the time it seems worse when it's warm and the dephaser pulley is rattling!
While I've got the engine apart I'd like to check and clean the injectors, if their resistance readings are in spec is there any other servicing I can do to them diy? Would it be worth sending them off to be cleaned by a pro? Will do hot and cold compression checks before taking the engine out too
Probably going to fit new ignition leads at the same time as new plugs, surprised at the cost of Magnecor ones though, I've already spent a lot of wedge on parts so as I'm changing leads as a precaution more than anything I'm reluctant to spend 90 quid on top!
Theres MLR high performance 8mm silicone ones on eBay for half the price, anyone had any bad experiences with these?
Don't bother with new leads - they either work or they don't...
Injector- my bet is it doesn't like the stale fuel. Put a few tanks of decent stuff through and see if it clears up, if not, second hand injectors are only £15 each.
Genuine tools only - the laser ones bend.
Quickshift - avoid IMO. The synchro's are soft enough in the box (don't rush your shifts or you'll get crunching at high revs which means box rebuild). New polybushed dogbone mount will improve it a bit, but otherwise it's one of the weakspots of the car.
Oh, and BTW, when you do the clutch, go with a Valeo one and you'll never have to worry about it again. Strongest part of a 172 on standard power.
