I have a 2001 Toyota Camry with 165k miles. This morning I noticed a damp spot under the rear of the car about where the tires are which smelled like gasoline. I just filled the tank up 2 days ago and haven’t driven it since other than to reposition on the driveway. Being in Texas, temps have soared in less than a couple days. I started to drive and got about a mile before the car started acting up. The RPMs dropped to zero and car surged as they jumped to 1.5. The car continued to surge and jerk until I came to a stop where the car idled normally for a few minutes, then dropped to zero rpm’s and died. It started right up, where i drove it to a mechanic. They have not been able to find any problems with fuel lines, etc. They have been able to recreate the problem, but unable to locate the source but have noticed a possible bad electric connection but cannot locate where bad connection is coming from. The car alarm has been randomly going off (always has since i bought it) with more frequency as of late and my dad believes that the only issue is the gas cap. There are no warning lights illuminated and no error codes that pop up. Any ideas?
