OK here goes, I am at the stage where I am going to scrap the car I am so sick of it. Have posted on another forum but had no luck so hoping someone can give me an idea.
The car is a 1995 convertible (uk) 2.0 gt manual which is the 3S-GE engine with 70,000 miles and full toyota service history. The symptoms are, from cold it will hesitate but not always straight away, could drive half mile before it does it. When it does I can have my foot to the floor and nothing happens. Then it surges and the car will run perfectly. EXCEPT if trying to drive at 20 or 30 mph it runs rough like its in the wrong gear. Driving at 35 and above it runs perfectly, Just to add to the problem, occasionally if I reverse and stop the idle will fluctuate and stall. Jumping the diag pins shows no faults! So far I have changed complete throttle body with sensors from a car that was known to run perfectly. Fuel filter, water temp sensor, air temp sensor, spark plugs, distributor cap, rotar arm, thermostat. As far as I can tell all vacuum hoses look OK I am stumped for ideas. Help appreciated. .

Injectors dont fail intermittent like that.

QUOTE (Special_Edy @ Aug 16, 2014 - 11:59 AM)  Injectors dont fail intermittent like that. Check the ignition coil I have no symptoms of ignition coil failure ( i dont think ) no problems starting, mpg seems ok. The reason for me thinking ijector is because one may be leaking or partial blockage or? I have no idea just clutching at straws, as the problem is only occuring from cold for a few minutes where I get the surge, then most of the time at low revs at 20 - 30 mph where it kangaroos or runs rough, at 35 and above it appears to run faultless. |
