You're wasting your money buying 98 unless:-you have an ultra high compression engine.-pressure built up in the cylinder will cause ignition before the spark plug fires.-you have an old beat up motor with carbon deposits that may ignite the air/fuel mixture prematurely thereby causing predetonation, pinging etc. Remember, the higher the octane the more resistant the fuel is to ignition. other half was complaining of fuel use and last night the strong smell of fuel around the car had a look under it today and run the engine, and fuel is leaking out of the fuel filter which is well rotten with rust have costed one up at £4.50+vat It looks like it has those daft fiat push fit I have a problem with injector 3 on my mk2 punto 1.2 8v elx which I bought off a friend 3 weeks ago car has run fine since 2 days ago then it was missfireing phoned rac because I was stuck without tools and a diagnostic.

Isti motor kao onaj 1.2 8v samo sto ima multipoint ubrizgavnaje. Ne znam ima li step motor, trebalo bi da ima, ali neka se javi neko ko bolje poznaje tu masinu. Drugaciji je to sistem nego kod onoga sa jednom diznom. Oct 11, 2011. #4. Try. 1. Visually inspecting the individual wires on the harness. 2. Clean the pins as best you can, smear with silicone grease (not silicone sealant!) and plug and unplug a few times. AFAIK, no schematic of the internal wiring of the ECUs is available. Assuming that this is the horrible nasty micro ECU that Mk2 8v Puntos were Right, now I am completly stuck. Changed lamda sensor yesterday no changes :bang: Did another comression test, just to make sure it is the HG before I take the head off. I made sure she was well warmed up, and started from cylinder nr. 4 this time : 4 15 bar = 217psi. 3 14.5 bar = 210psi. 2 14 bar = 203psi. Wet =. cyl1 - 200psi. cyl2 - 200psi. cyl3 - 200psi. cyl4 - 200psi. It was sad news, the compression had gone in cyl1, that is where my oil was burning from. This was a cold compression test, not a hot one. Turns out my rings had worn out - allowing the piston to start rubbing on the sidewalls, the engine was scrap. dl9h.
