NEW PROBLEM - RUNNING STRANGE

Forum: 

SPORTRAK , 1.6 16V G REG , CARB MODEL.

WHEN ITS COLD IT STALLS AT EVERY ROUNDABOUT AND JUNCTION.
WHEN ITS HOT IT RUNS AT 2000 REVS,

ANY IDEAS,

Choke

Automatic choke is probably sticking. Or more difficult - a temperature sensor is faulty.

Try removing the air filter to get access into the carb. Start the engine. Get someone to rev the engine high - or diy at the carb. Using cotton sheet [no fluff or it gets sucked into the engine]or similar foldered into a big wad and push over the intake to block the air intake but do not kill the engine. The 'suck' will suck any blockages and possibly free the choke.

Alternate ... buy redex. Do as above but do not use a cloth wad. Simply slowly pour redex into the car and let it tick over - tick over as slow as possible. After a few minutes rev the engine .... lots of smoke ! If you cant get redex use thin engine oil.

If choke is free/improved mix redex into the petrol tank. Also buy a fuel additive and add to the tank next time you fill up.
