1988 Toyota Landcruiser Repair Question
1988 Toyota Landcruiser Acceleration
1988 Toyota Landcruiser 6 cyl Four Wheel Drive Automatic 225000 miles
The car has a new longblock and transmission and has run fine for a year. We have spent $21,000 so far. ALMOST everything is new.
It runs FINE when it is cold or warm for the first 15 minutes. Then, and i can not say how suddenly, you can not depress then throttle without major hesitation, roughness and NO power. You have to feather the pedal to get the thing home.
I can not continue to pay $80/hr for diagnostics. The catalytic converters (2) have been checked OK.
THIS IS ONLY WHEN IT GETS UP TO FULL TEMPERATURE - it does not overheat. There are no ECU codes.
Please do not recommed the usual suspects unless they are specifically related to a MAJOR perfomance change due to temperature - i can not go through the littany of all things we have done. I did disconnect the EGR birefly and drove it - that did nothing to fix the problem.
Can i disconnect the temperature sensors to track this down?
Ok you have spent a bundly on this truck now lets see if we can find the problem. Now I am going to send you a couple of tests to do you will need a digital multi meter and you may at one point need a test light you may not.
Now first you will need to have a set of brass feeler guages and you will need to check the gap on the pickup coil in the distributor. I will include a pic so you know where to check ok. The gap must be between .008-.016 inches. Do you have access to a scan tool? Does any of the parts stores in your area do a free scan? We may need a scan to see if any codes have been stored.
Next we will do an ignition coil and pickup coil resistance test ok. Then we will check the ESA (Electronic Spark Advance) unit. Get back to me with what you find and we will go to the next step.
