Hello All, I'm just posting my first thread so you'll have to bear with me as the old grey stuff is just not what it used to be. I own a 1995 civic 1.5 lsi 4 door saloon with a D15B2 engine fitted with a dual point injection system. I bought it in 1998 with 17,000 miles on the clock. It now has 141,000 miles on the clock but it has always been well serviced by myself and has the oil and filter changed twice yearly. It hardly uses any oil and still does 37mpg, the same as when I first bought it. In the main it has been a really great reliable car. It has always been a bit fidgety at low speeds but has always ran smoothly at higher speeds. It has recently started to stutter and falter at lower speeds especially when pulling away from junctions or slowing down but only when warm. When the engine is cold it drives faultlessly and smooth as it should. The fault only appears when the engine is hot. I have fitted the following new blue print parts; sparkplugs, HT leads, rotor arm, distributor cap, air filter, fuel filter and all the small vacuum hoses. I have ran an injector cleaner through the fuel system and all the electrical connections appear to be clean and tight with no signs of corrosion but the fault is still there. I have tested the coil primary and secondary resistance. The primary resistance appeared to be correct (between 0.6 to 0.7 ohms) but I got no reading at all on the secondary circuit (coil + terminal and the coil connection where the spring contacts the distributor cap. I bought a new multimeter for the job so I doubt that it is at fault.I have had the distributor out and although there appears to be no play in the bearings the shaft does appear to ratchet round somawhat. Is there some type of magnetic pick up inside the distributor body? Is it possible for the coil to be defective but for the engine to run smooth when cold but faulty when hot?. Any suggestions please. Old Maddo
