Suzuki 250 bad spark plug symptoms8/25/2023 Before I started having issues I had the bike at the Suzuki dealer to install my original TPS sensor because I bought a used throttle body that had a modified butterfly valve and bike was getting hard to start and running slightly strange (Rough) at times and when I had it the bike hooked up to lap top we thought the TPS sensor was the problem. The plug in it only has 4-6 hours on it and looks perfect. I've changed coil, condenser,rectifier, IAP and TPS sensors had the Vortex tested at Vortex good and I also put a good used 15 fuel pump on that seems to pump more fuel then my original one. When I checked coil it was easy to get a reading and it was in spec. Id suggest speaking to someone who knows about these cars (a dealer, restorer. Shouldn't have had that hard of a time getting readings. Therefore a hot plug will not necessarily be bad for your car in a hot country. I had a really hard time getting OHM readings on the Stator, but once I did they were in spec. Bike acts like its out of time? I'm thinking maybe crank position sensor. There are two ways to deal with a bad spark plug: Clean it if it’s dirty, or replace it if it’s not. RELATED: 5 Symptoms of a Bad Engine Control Module (ECM) Engine Control Unit. It gave a puff of air once wouldn't call it a back fire. How Does a Bad Spark Plug Sound There are only two possible sounds that may indicate a bad spark plug: Your engine running rough, even though it’s supplied with fresh fuel, or the silence of it not running at all. Since spark plugs assist in starting the engine, its likely that bad spark plugs will impact the engine through misfiring, surging or. We will optimize both the ignition and the fuel ECU SELF-DIAGNOSIS: If the. I looked pretty closely, but just couldn't find any type of part number on them, maybe it wore off? All I could find was a stamped on "Made In Japan" on the top.Johnny89superbike- I got a new wiring harness and bike still won't start. Here are the symptoms that matter the most. Defective plugs can also lead to a misfiring engine, a rough idle, trouble accelerating, a hard-starting engine, decreased fuel economy and exhaust that smells like fuel. Oh, and the plug caps look like the LB05E's, but the dimensions are different than any of the ones on that spec sheet. Estimated repair costs for engine code P0300 Spark plugs, 66-250 Spark plug wires, 180-240 Fuel injectors, 1500-1900 Ignition coils, 230-640 Vacuum. Symptoms Of Bad Spark Plugs If the Check Engine Light is flashing, the spark plugs may be bad. Outboard acceleration decrease and engine power loss can occur when the spark plug is overheated. An outboard losing power could lead to decreased acceleration and even total engine failure. It was a points & condeser kit for a T350, though, so you'd think they were about the correct capacitance. Outboard Engine Losing Power/Decreased Acceleration Loss of engine power is another symptom of a bad spark plug. There are a number of signs that give you the heads up that your spark plug is fouling or is already fouled. The condensers I just put in are new, but they're off eBay, so not sure how good they are. Maybe I should just wait to see how it runs, but I thought that if you had a lot of sparking at the points it would burn them up quick, or it indicated bad condensers. The most common causes are problems in the ignition (for example, a bad ignition coil) or fuel system (for example, a clogged fuel filter). That kind of backs up what the PO said, that it was running before he started taking it apart, but then lost interest. When your engine cranks but wont start or run, it could mean your engine is having trouble producing a spark, getting fuel, or creating compression. The timing is fairly close, judging by the timing marks through the little window and using my multimeter to sense the points opening. I haven't accurately set the timing, since I haven't tried a 1st start yet (I'm still waiting on a set of JEMCO pipes, and don't have any other pipes to put on it, since I sent the old ones to be used to develop a fixture to make the new chambers).
