Car Forum / Mazda / Mazda Miata / March 2007engine noise in radio
Dear all -- Since my Miata's back from the dealer, I can hear the engine in the radio. I presume they were fiddling at the ignition, because the transmission belt has been changed. Before I head back to the dealer - is there a straight forward source of error that I might check myself? Car is a 94 european MX-5. Thanks .\\arc "I can hear the engine in the radio." My first suggestion would be to take it back to the dealer and make him fix the problem that he created. As to what it might be. Loose antenna cable at radio or at a pigtail plug/socket. Poor ground at radio, or antenna, or engine. Bad plug leads. Non Resistive plugs. Worn Alternator brushes "transmission belt has been changed" ?????? Perhaps you mean timing belt? Miata's are a reasonably simple car, but they do not use a transmission belt. So what did the dealer really do, and why did you take it to the dealer. > Dear all -- > [quoted text clipped - 9 lines] > Thanks > .\\arc > "I can hear the engine in the radio." > My first suggestion would be to take it back to the dealer and make him fix > the problem that he created. I know. It's just some distance away, and I didn't want to take two hours if there'd only be a cable to juggle to fix it. > "transmission belt has been changed" ??????

Timing belt, sorry. I'm not a native english speaker. And that's the reason I took it to the dealer, the original belt was on it for 13 years which made a bit nervous. From looking at the engine, I was guessing the valve cover needed to come off for that, and therefore the ignition plug cables had to be removed. The cables look tight and orderly, so I wondered if there's something else to check. Thanks, .\\arc It's quite possible that the spark plug wires were damaged in the process of removing them. If the wires are several years old, they need replacing anyway. The standard recommendation is to use NGK "blues", an OEM approved replacement carried by most Mazda dealers. There is a way that you may be able to test the wires, although I have had poor luck attempting it. Basicly, an ohm meter is connected to the ends of the lead. While one person holds the meter probes and the ends of the wire, A second person wiggles the plug wire. If the wire has any small "opens", the ohm meter may show an unstable reading. > > "I can hear the engine in the radio." > > My first suggestion would be to take it back to the dealer and make him fix [quoted text clipped - 20 lines] > Thanks, > .\\arc |
