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. .

My car (7A-FE, 285k) had a very similar issue. It would hesitate from a stop and occasionally stall when COASTING to a stop. At around 2,800 RPM (my cruising RPM) the car would jerk violently and would be unresponsive if I slammed the gas down (did so just to test). I suspected TPS and replaced it, along with a tune up (cap, button, wires and plugs). The problem went away completely for a couple of weeks, but then I started experiencing similar issues - hesitation, surges and very poor idle. After a 3 hour highway trip I replaced my fuel filter and again, the problem went away completely. Keep in mind that these separate occurrences may be completely unrelated - the symptoms were all similar, however. What sucks is that you already replaced these parts. Do you know from first hand experience that the donor car was running properly? If not, maybe they got rid of the car for the same reason.
Have you had ANY improvements since replacing the parts you mentioned? |
