Engine Performance problem
1991 Other Nissan Models 4 cyl Front Wheel Drive Automatic 217000 miles

I am using 1991, Nissan, Pulsar GTI sedan.
Engine not running smoothly, Hard to climb up hill, engine slow downs to 10Km/hr. I have to wait for 5 to 10mts in the morning to warm up the engine, otherwise, it is hard to drive, specially climbing up. On flat road, no problem.
I took it to a mechanic, he could not find the fault, he said might be the air flour meter. Done electronic diagnostic check, did not find any problem.

Changed oil filter, oil, air filter, sparl plugs etc.
Still no change.

Much appreciated your comments.
