- I have a 1983 Nissan Pulsar NX (1.6 l, 4cyl, Carb. Inj.) with the following
- problem. At first the car used to die out on idle (at stop lights etc.).
- It would start back and run fine until the next stop. I did not seriously
- bother with it then (about 2 weeks back).
-
- Few days back it started stalling badly while driving. When I stopped the
- car and started again it ran fine. This problem occured a few times again.
- When this stalling occured the car moved in jumps as if I had pumped and
- released the accelarator in spurts. Yesterday I barely managed to drive
- back home from work (2 miles).
-
- Today morning I could not drive the car at all. It would start and immed.
- die out. Pressing the accelerator had no effect. I could rev it up by
- pumping the accel continuously. But as soon as I stopped this, it died
- out.
-
- I had the car towed to a repair shop. The mechanic says it is a carburettor
- problem and replacement would cost $300-$400. He said that he could make it
- run a little better by advancing the ignition timing to the max.
-
- After this adjustment the car idles fine. I can also rev the engine by
- pressing the accel. It also drives fine for a short while after starting.
- After that the same stalling comes back. At idle the engine rpm sometimes
- seems to lag the accel for a second or so. This lag is very pronounced
- while driving and moves the car in jumps.
-
- I'm not so sure that it's a carb. problem since it runs fine for a
- short time after starting. Also advancing the timing seems to have helped
- at least on idle.
-
- Now for your advice:
-
- Is this really a carb. problem? If so can I fix it without having to
- replace the whole carb.?
-
- I would like to fix the car myself. Any suggestion from you folks will
- be of help.
