As an update, 2 months later and I finally got a fuel pressure gauge on it. 40 PSI at idle. Drops to 30 PSI under acceleration.
Bad fuel filter? Or bad pump assembly.
As a side note, I read someplace there is a check valve in the system to hold the pressure that is achieved during the 1 sec...
Thanks for the advise on the fuel pressure, but wouldn't this throw a code? I guess not since there is no monitor, but what about lean?
It's too even/smooth/substantial of a surge to be just one plug or plug wire. Really does not feel like a spark issue. Maybe advance tho??
Hi,
Wondering if anyone ever experienced a surging problem with their Viper? During hard acceleration is noticeably surges, and is generally low in power. Sometimes pulls reasonable...next moment less power. It is not showing any codes when read with an OBD II reader.
The car only has 15K...
