Good point, I'll try it tomorrow.Toss a scan tool on it anyway. Often times you'll find pending codes that don't trigger the check engine light, simply because the problem doesn't persist long enough.
Automatic, could it be a problem with a speed sensor?Manual or auto?
140,000. In the past two months, I have replaced plugs, plug wires, air filter and fuel filter. Before changing the plugs and wires I was getting a #3 cylinder misfire. After plugs and wires, no #3 misfire, but the mid to upper rpm surge was evident. Surge is still there after the filters were changed. #316 code was triggered for the first time yesterday.P0316 is a misfire on startup for the first 1000 revolutions. How many miles and when was the most recent tune-up done?
I have a fuel pressure gauge, but I don't see a stock fitting on the fuel rail to hook it to. How do you go about checking the pressure on this system, splice into the fuel line and install a gauge? Is the attached picture showing the regulator, if so, do you install the gauge before or after the regulator?Check your fuel pressure under load. Could be a fuel pump going out.
A couple of posts back I explained the #3 misfire code I had before replacing plugs and wires. Since then, no #3 misfire. At that time I suspected the coil, but didn't see anything wrong with it visually. Autozone claims that they can't test the coil pack, I didn't want to just swap it out on a hunch. Is there a way that I can test it out. Can the coil have an intermittent problem and not send a trouble code to the computer?Yeah don't splice anything, if there isn't a schrader valve on the fuel rail you can get an adapter to go inline before tw fuel rail. But let's not get ahead of ourselves, if you are getting a p0316 now id suspect your having an ignition related intermittent misfire. Check the coil. Sometimes they will get hairline cracks on tw bottom of them. I see it all the time.
buy a 5.0 lolThe engine idles smooth, no trouble codes, but the engine surges at the mid to upper rpm ranges while holding the throttle steady. I have replaced the air and fuel filters, spark plugs and plug wires. Where do I need to look next?
