1999 Nissan Quest chugs and dies when hot

ShootingStarz's picture

Up until last week, my Quest did great. It started hesitating, chugging and losing acceleration. After that, it dies. It doesn't start, again, until it cools down.
My husband replaced the fuel pump and thought that was the problem. It did it, again, today. It didn't take as long to start this time, however. Before, it was taking about an hour or longer. It started up in 15 minutes while ago.
Any thoughts?

I had the same problem, changed everything. I just sent back a knock sensor, thats a $ 700.00 job. A NISSAN TECH. in another forum, said to change the DISTRIBUTOR. REPLACE WITH A NEW ONE. THIS CHANGED MY LIFE. MY QUEST RUNS NEW. Bought the dist. on e-bay for $ 148.00 & free shipping. There is a photo cell in the dist. that either gets dirty or goes bad.Thats why he wants new. I had glowing cats. and everything else. My 2000 sat for six months, while I replaced everything. It use to run good for about a mile. Now its great. GOOD LUCK ROGER S

Chugs and dies when hot

I have the same problem with my 2000. Unfortunatly I have not found the answer; but I can tell you what I have done that has not fixed the problem. If you find a solution; please let me know - Thanks.

Replaced all plugs, wires, distributor cap, catalytic converter. Still happens. Considering ordering a used ECU unit just for the heck of it. That unit controls gas and firing among other things.
