2.5l running lean... - 3/17/2008 7:53:58 PM    daksport91   Posts: 55 Joined: 10/23/2007 Status: offline got a 90 daytona 2.5L had head gasket done last fall... drove it for a month or two, then was parked.  It has sat for just over a year, and it had been started and moved around a couple times throughout the summer.  Went and fired it up a couple weeks ago( started like a champ btw  ) but now it is running lean and im not sure why. i changed the fuel filter and have a fresh tank of fuel in it... seems as if it is getting to much air ??? any ideas?

The fuel pressure reg on my shelby went out, and it was letting air in and running lean. I unhooked the vac line to it, and it got better. _____________________________ -92 White IROC RT http://www.cardomain.com/ride/2038370 -87 shelby z with T tops Best Turbododge site--->www.turbododge.com (in reply to daksport91) Post #: 4

And the vac line you need to unhook goes into the side of the regulator. _____________________________ -92 White IROC RT http://www.cardomain.com/ride/2038370 -87 shelby z with T tops Best Turbododge site--->www.turbododge.com (in reply to daksport91) Post #: 6
