Since installation of mods, engine "revs" itself when I start it up, until it warms up (revs from approx. 600 to 1100 rpm), then idles smooth, once warm.
Since then, it has also has been "chokey" when pressing down on the accelerator. RPM's climb okay from 600 but then there is a an almost "popping" sound and the engine starts to choke out.
So, that makes first gear interesting -- if I don't give it enough gas the engine will die out completely.
So far, that has not been a huge problem. But, yesterday, I went to shift from first to second and, upon disengaging the clutch, and giving it gas, the engine sputtered and died completely.
Restarted it, and discovered that it is now choking itself out between approx. 2400 to 2800 RPM's. Giving it more gas, with the clutch disengaged, only makes it choke out worse, again to the point of the engine actually dying.
With clutch engaged, it revs fine -- no choke out.
Shifting gears, if I shift below 2400 RPM or above 2800 RPM, from any gear to any gear, it does not choke out, engine stays smooth.
But, let out the clutch in that range of about 2400 to 2800 RPM's, when shifting up or down, and it chokes out, to the point of killing the engine.
Also, letting the revs drop into that range, say, while cruising in 4th, slowing down, and the revs drop below 3000 it starts to choke, and giving it more gas only makes it worse. If I put in the clutch, rev it back up above 3000 and let the clutch out, it's fine again.
Currently, I'm driving it by making sure to shift either below or above the problem RPM zone.
I'm in Seattle, and there I don't know of any reliable Mazda repair place -- only ones I know that work on these charge a fortune and want to replace half the car whether it's needed or not.
Anyway, any help that could be given would be very much appreciated. Thanks!
have the same problem?
