Good call, as I've had issues with this in the past. Not it this time though, as confirmed by datalog and corroborated by Jeremy at FM: "Your ATS & CTS look fine. .."
That was actually the first thing I checked. From: [email protected] Date: Tue, 3 Aug 2010 14:21:03 +0100 Subject: Re: 94 FMII Cutting out at high boost/rpm To: [email protected] CC: [email protected] Checked the intake air temp sensor readings? My car has similar issues a few times in the past, the first time was the sensor itself, subsequent times the sensor's ground wire had a break in it. When it happened the air temp would go to 100, felt like you'd stomped on the brakes. Steve On Mon, Aug 2, 2010 at 11:14 PM, Robert M <[email protected]> wrote: Greets! My 94 FMII car (installed circa 2000, RC550's, 12psi, BBBT, original fuel pump) is cutting out under high boost/high rpm conditions. I sent a datalog to FM and Jeremy replied, "Your ATS & CTS look fine. You've got plenty of injector on-time. So, if you're leaning out I'd have a look at your fuel pressure to see if your pump is bad or filter is clogged. Should be running around 35 psi at idle & around 45 psi if you pop the vacuum hose off the regulator. In boost it raises pressure 1:1. " I finally checked the pressure today and got 35 idle/44-ish with the vac source removed. Max pressure (checked with the fuel line output blocked) was ~77psi. I did notice that the behavior doesn't start immediately, but rather appears once the car is good and warmed up. What's the next step? I probably am due for a filter, but it seems somewhat unlikely that I'd get good numbers in the garage with a clogged filter, no? All input welcome- thanks in advance! _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower
