1991 Mercedes 190E 2.6 Manual, Cosworth Kit.

So in May I bought this:






















It,s a 1991 Mercedes 190E with 188K on the clock and a 2.6 Manual swap (183K), Cosworth Body Kit, H&R springs and shocks, and OZ Futuras and lots of lovely new suspension and brake bits put on by BigKev30 on here. Love the car.

I got it replaced the Alternator and Battery, fresh fuel and she fire right up and purred like a kitten. Drove it around the yard and apart from some rubbing on the front arches and a noisy gearbox (already described in the forsale ad) she seemed almost ready for MOT.

However she's recently developed a no starting/poor starting, no idle fault. When she does run it's lumpy, misfirey, rich and no power. So I've been playing around with the old Bosch K jetronic. Adjusting the CO screw on the flow meter/fuel head hasn't helped. In fact I may have made it worse.

So servicing the brakes and checking out the gearbox and clutch have gone on hold while I check out the fuel system from back to front.

Plan is to: check and replace fuel filter (if necessary), check fuel pressure is in spec and adjust. Remove injectors and clean/replace them and the seals, clean the IACV, check the plate in the air flow meter is properly centred (it did get stuck at one point but I think that was my poor adjustment).

I'm having naughty thoughts about 2 sets of Triumph 955i throttle bodies and a megasquirt/speeduino to run them, keeping the stock ignition. But I'm not well versed in the art of changing engine management so many nights of googling will be required before I take the plunge. Hopefully I can get the old Kjet functioning properly and have it MOT'd soon.
