Any ideas plse...

1980 - runs really well but dies when returning to idle - if i catch it and give it some gas all is OK, if not revs just drop and it stops - starts again no problem.

What could it be?

Thx - happy holidays all

Try setting the idle adjustment screw.

 

Will check thx - however it was running fine - and hit this problem in the last week - have checked plugs and points - all ok - very mysterious

 

You have the points ignition in that or the electronic? My 1980 had the electronic Hybrid Ignition.

 

Does this happen all teh time, or only when the car is warming up? It is probly and Idle issue. My car changese it setting all the time... it used to idle at 1250rpms then one day it decided to idle at 500-750 rpms ( depends on the day)

 

post this in the first gen section they can help you out alot more. People allways have this problem

 

thx all - have been off line a few days eating too much turkey....glad to hear its a common problem....am still a relatively new RX owner so am getting used to what is normal.....

happy new year

If you still have this problem, and if it is happening mostly on colder days even after the engine is warm you might want to turn your idle mixture screw out about one to one-and-a-half turns. This will increase your idle speed, but if you turn the idle speed adjust screw inward your idle speed can be returned to normal.

On days when the ambient temp is lower than say, -10C the colder air coming into the engine is more dense than normal--- even if some of it is coming in via the exhaust heat duct. This more dense air means that the car is, in effect, running lean. The weight of the fuel vs. weight of air entering the engine is thrown out of whack since the fuel coming in is the same amount as on warmer days. Only the amount of air has increased, diluting the charge. These older cars do not have mass air flow sensors to correct the air/fuel mix.

A richer idle mixture will correct this, but you'll want to set it back to where it was once the weather warms up.
