That's a similar problem I was originally chasing. Turns out my battery was sliding into the computer wiring harness disrupting sensor / injector input and output signals. I cured my problem by placing a 1" spacer on rear battery clamp pushing the battery forward, and this cured my problem. Also may or may not relate, my vacuum canister was completely full of crud (replaced) and the line leading to the carb was cracked (vacuum problem). Also my jeep would lurch/buck and such after a 20 min cool down for a couple of seconds then stop. I traced this to a bad o2 sensor in exhaust manifold.

Its just a guess. sure. heard this years ago , before 1988?
sure.
but is not now. the tank has the pump and runs up to 60psi pressure
preventing vapor lock.
why not post the symptoms and let skilled diagnosis win?
my wild guess.
engine stalls?
or engine bogs (lost power up hills)
what?
ever get a 60k mile tuneup? eva?

Vapor lock is something for carberated cars. Modern fuel injected cars have fuel pump in the tank and the whole fuel system is pressurized.

Why do you think you have vapor lock?

SOURCE: fix vapor lock

If an EFI model the run the fault codes and fix the faulty valves and solenoids . If a carby model the re- route the fuel lines away from any heat source. Put a fibre gasket and heat block ( bakelite material that does not conduct heat up from the manifold) under the carby to manifold and if all else fails put a small filter in the line before the carby

Does anyone have suggestions on a 2002 Altima that has vapro lock?

Vapor lock is caused by fuel getting too hot in a fuel line or fuel rail and is rare since modern fuel system circulate fuel fro the tank to the fuel rails and then excess goes back to the tank. Are you sure you have vapor lock? Please describe all symptoms.

I would forget the vapor lock theory. It ran okey for years,so why not now
Vapor lock goes back 35 years to carburators and road race cars.
Do you ever get a Mil Light on dash or stored codes?
What tests were done to warrant O2 Sensors?
Did you have any overheating issues,or just thinking so?
Don't overlook an old and partially blocked converter. You haven't said what your drivability issues, really are!
Fuel systems aren't really to heat sensitive or know when summer is here.
You need to think simple, Ignition,fuel filter,pump could be partially plugged and working, but not much volume.
Tape a fuel pressure gauge to windshield and go for a drive.

95 jeep wrangler overheating and hissing sound

Had the same problem on my 95 Wrangler within the last month. I was told that the radiators on Wranglers tend to wear out, and don't push fluid through after 10 years or so. I decided to 'fix' everything at the same time. I replaced the radiator, the radiator hoses, and the water pump. That stopped the leaking, and fixed the problem. Water pumps run less than $50, and is actually something you can do yourself. I'm not mechanically inclined, but I needed to save the labor charges from the mechanic, so I took at shot. I had no problems. It does help to have an extra pair of hands to replace the serpentine belt.
