Check this and see if it's not your problem. If so, then it's likely a fuel delivery problem. And that's what economy coupes are all about. The K-series all have a 7,000 rpm redline with 7500-7800 rpm limiter, which given the engine design is conservative. Bad air supply, poor idle.
But the automaker also had to keep the K8's displacement below 2000cc to avoid extra taxes in Japan. It was a 4-valve design with and a bore and stroke of 75 mm × 69. The ignitor can be tested at a parts store. . I do however know my fuel injectors do need cleaning, he hasn't ruled that out either.
It was used in the T-platform cars. If spark is good, check fuel filter, fuel pressure, check timing marks on crank pulley and cam marks, Try a little starting fluid in the air intake and see if it runs for a moment. Clattering on acceleration, herky jerky idle. This effect optimizes volumetric efficiency over a given rpm range to provide maximum torque over the entire rpm range. Hmm sputters, and rough idle can be from poor air circulation, as well fuel delivery.
Please help by introducing to additional sources. A weak or sporadic spark could be a bad coil or coil pack, or a bad ignition module the ignitor. The valves actuate at particular engine frequencies i. Mazda introduced a key technology with these engines, known as the. A series of two butterfly valves coupled with electronically controlled actuators varied the volume and length of a resonant chamber within the intake manifold. This compact Mazda also had superior styling and the largest glass hatch one could ask for. If no change, then it's likely an ignition circuit problem.
Posted on Oct 22, 2010 Check for a blue snapping spark on 2 or 3 plug wires or all of them. Relevant discussion may be found on the. The K-series also features a highly rigid aluminum split-crankcase engine block design with 4-bolt mains with additional bolts securing the lower block, an internally balanced with lightweight powder forged carbon steel. The supercharger used is the with electronic boost control. Have you pulled any code on it? A Mazda K8 engine block. If you get good spark, then ignition is likely not the problem.
Based on the principle, the intake manifold is equipped with 3 chambers tuned to a specific resonant frequency. I had to go back to a factory pulley, and presto - problem fixed! Your getting your gas, thats evident, but are you getting the required amount. In the end, the 24-valve dual-overhead cam 1. Despite a bit of body roll, you got a lot of fun for the money. November 2018 Mazda K engine Overview Production 1991—2002 Layout 60° 1.
The computer dynamically switches between each resonant chamber to achieve the appropriate resonant frequency for the engine's rpm. My mechanic's diagnosis is bad valve cover gasket causing oil to seap into the spark plugs and bad timing belt, which I have not replaced at 150k miles. Took about 30 seconds to pop the hood and pull it off, 3 minutes to glue it back together, an hour to dry, and 30 seconds to reinstall it. That pulley, while saving a few horsepower, spun the alternator slower, and didn't produce enough juice to charge the battery at all - at idle I would kill my battery within the hour. Check the coils with a volt-ohmmeter per the specs for your car. Also, it idles poorly after it is warmed up and the problem gets worst.
It featured solid lifters, a cast crankshaft to reduce rotating mass and a reworked intake system. This article relies largely or entirely on a single. The valve operates to create three specific first-order resonant frequencies that increase cylinder air charge. I have read on engine knock sensor going out on some of these also. Well, Mazda needed a premium engine for its Eunos luxury brand which flopped in a big way. The displacement was held under 2000cc to minimize the annual Japanese obligation. Why make a tiny V6? They were designed with the intent of being as compact as possible for short-hood applications.
Also no check engine light at the moment. Pulled a code multiple cylinder misfire. Above that threshold, the first primary resonant chamber is again used, but at this engine speed the pressure wave from the second-order resonant frequency aids in charging the cylinder. . . . .
