Not the TPS - Got the right specs for the XT TPS! Not the CTS - Removed and tested OK! Still have Q's about the MAF sensor. BR - less than 10 ohms B - 70 + ohms Tested B back to the ECM. Tested OK. .3 ohms between ECM and MAF. *When the car is cold, and the green connector is connected, there is a noticable change in the timing. When the engine is warm there is not a change at all. Any ideas??????

updated original post! Checked the TPS andindicates as follows: Ohms on lead 1 and 2 is only 1.4. Ohms on lead 1 and 3 with throtle closed is 9.??. Ohms on lead 1 and 3 with throtle open is 2.??? I think it is bad. Also, One of the grounds on the MAS indicates that I have a bad ground. The manual indicates to start looking at the intake manifold for possible bad ground....I do not see any ground wires directly to the intake manifold. Any ideas where it is located?

1989 GL-10 1.8L EA82 MPFI (from 1988 XT, i believe) Original Enginge - 1.8L EA82Turbo MT Just installed new timing belts, and have everything lined lined up with the timing belts (Flywheel marks and cam shaft pullies). Set the timing on the engine 20 B with green connectors behind dash together, but timing does not change when conectted. Car runs good!!! After driving for a while, the car looses power and does not accelerate. There is a backfiring on downshift. When geting back and checking the timing, I can not even see a degree mark! Once the car cools, it will run well, and the timing in OK. Other recent work: Front CV boots x 4 Exhaust manifold gaskets New Plugs New cap & rotor **********UPDATE*************** Disty bolts are tight. Error codes: 22, 32, 33, 35, 42, 51 Is code 33 a normal code because the car is not moving? Is code 51 a normal code since the car is in neutral? Car ran at a high idle (1250rpm) before starting. When tuning, lowered the idle to the Factory Rec. of 700rpm. Set timing to 20B.

Is there a way to switch a digital speedometer from MPH to KPH? I am going to be in Central America for 7 months and would like to convert the system to metric. I am thinking that this is a ECM issue that can not be done, but trying to see if anyone knows. 1989 Gl10 w/ 5 speed manual trans Thanx
