Ok, got a few issues including the engine not starting now but more on that later.
Short update- have ordered another 2 MAF's from the states to Oz. It appears though that it could be operating ok.
The SPFI TPS test has been completed. I'll try to simplify this as best I can. There is a problem.
According to the detailed test this was done as per proceedure.
Step1/ Checking continuity between terminals A and B
action- checked and ok.
Step2/ Check for continuity after inserting a thickness gauge between the stopper screw and stopper. Using an ohmmeter, check that continuity exists between terminals A and B, when the throttle is fully closed, and that no continuity exists when the throttle is fully opened.
action- checked and ok
Step3/ Insert a feeler gauge (thickness gauge) of 0.0122 in. (0.31mm) between the stopper screw on the throttle chamber and the stopper (this corresponds to the throttle opening of 1.0 degree). Ensure that continuity exists between terminals A and B.
Insert a feeler gauge (thickness gauge) of 0.0311 in. (0.79mm) between the stopper screw on the throttle chamber and the stopper (this corresponds to a throttle opening of 2.5 degrees). Ensure that continuity exists between terminals A and B.
result- .31mm feeler ok, .79 feeler not. Adjustment requiredas per instructions which are
" If above specifications are not as specified, loosen the throttle sensor attaching screws, then turn the throttle sensor body until the correct adjustment is obtained."
Step4/ "Throttle Opening Signal"
Check continuity between terminals B and D, then terminals B and C
Using an ohmmeter, measure resistance between terminals B and D, then between B and C (changes with the opening of the throttle valve).
The ohmmeter should read 3.5-6.5 kilo-ohms between terminals B and D.
Result- B and D is 4.7 ohms- ok.
Result- B and C is 0.5 ohms throttle closed- ok (less than 1.0). Throttle fully opened - 4.9-5.1 ohms....far in excess of 2.4 ohms.
Now interesting enough the reading of 2.4 ohms (its suppose to vary with increase and decrease of throttle) occurs at half throttle right where the dead spot begins.
I assume this sensor is RS!
The battery has been on trickle charge. Took it for a test run. The engine certainly started well and idle was nice and not as high when first started as it was previously- good. Got it home and revved it and it misses beyond half throttle!!! bogs down, loses revs.
Then the starter motor strained to turn the engine over. Connect the charger to the battery and it indicates fully charged. Turn ignition on and eCU connectors and find ECU code is 3 long flashes in addition to the 5 quick flashes it normally has for model designation. Check the trouble shooting manual and cant find 30 in the codes but 31 is throttle sensor.
So has adjusting it to achieve the second feeler guage setting upset the sensor for higher revving? Gee....I'm at a loss. opinions?
