Question about 1966 Ford Mustang

1 Answer

66 Mustang- 289 V8- has an intermittent surge and rattling noise

The car has sat for almost 2 years, relatively low miles on a rebuilt 289 about 3 years back. It's been surging on and off for the last couple weeks, just replaced the fuel pump but it didn't fix that problem. Also have a rattling noise on initial accelerations and if I really get on the gas, but it's an occasional problem also, what should I do?

Sounds like crappy gas. The 289 may not like pump no-lead and the rattling sound you are hearing may be pinging / knocking.

No if the oil light has flickered you have oil pressure loss some time just belive the sensor do help us out. lifter do not cause oil pressure loss pressure is built in the rotation of the crankshaft. The knock under the plenum will point you to that cylinder that is affected, (main bearing) as for a 1995 the injectors can only cause a misfire but no knocking noise,will they honor the warranty

How do I identify the make of my 2-barrel carb -


The OEM carb on this model was Motorcraft, and you can get the rebuild kit from Ford or you can look up the model number either in Chilton's manual for that car, or maybe find another (kinda hard nowadays) carb in a junkyard and maybe it still has the tag. You can also research the specs for that motor on a web page of Ford or 2nd party auto parts dealers. I'd bet most mechanics over 40 years old could start you off in the right direction, too.
