Would you know how to eliminate that running out of gas syndrome?.....that's what it feels like and it is obviously a common problem with the late eighty's to 91 models with the 351 and V.V. carb. Checked everything..replaced: distributor, dist. cap, rotor,....coil,..plugs & wires...brain-box. Its getting fire...and its getting gas...no clogged filter. Replaced: filter, fuel pump and plenty of gas dry! vI've replaced all of these items and more including a regular 2bbl carb for the V.V. I even replaced both cats and the entire exhaust system. I finally quit driving it!.........I used 2 think it was a unique problem with just my 91 ex-police CV.....now I have the same problem with my 87 with a 351 (this was an ex-government car)...same thing.....ran fine....then all of a sudden....it has the exact same symptoms as my 91 did....I used 2 think it was bad gas or water in the gas..put some gas dry in it....that didn't do it ......but that's what it feels like,,,,,the symptom is your going along...at highway speeds and been driving for a while when all of a sudden....it feels like your running out of gas.....U let off of it. Then it comes back ..and goes a little further..then the same thing happens and gets progressively worse and more frequent until your almost crawling or it just will not run at all!.....This only happens after the car reaches normal operating temperature. The warmer the day is the earlier this will begin to happen. There has 2 be an explanation..I need 2 fix this . It is quite embarrassing and not 2 mention.....very unreliable with this condition. I hate this! HELP! Rich
P.S. I've heard of this condition before a while back but don't remember what the solution was..maybe the EGR or something but I need details.
