Use a meter and start checking. I hate throwing parts at it. Temp sensor seems like a good call though! You need to go through the adjustments. It isn't the same critter as the OBD 1 Jeep. You need to baseline the sensors so the ecu has a good refrence for each. The temp sensor has a resistance chart in the manual to check it's function. Glad to hear its running.

It's setting more then just a scale. You need to set it to the correct mode. The manual might help but you should have a selecotr switch to read voltage ac, voltage dc, current, and resistance. You need t set it up first then select the scale. The readings on the scale must be higher then the expected reading when you set the range. You tube has some video's and if you can look up the brand on line and find the manual I can help you set it correctly.

You can measure resistance with voltage present/vehicle running. Volt meters use their internal battery to power the circuit you are testing when you measure resistance. Sening you a pm with my number. Call me.

Ok heres where im at..

Got new coolant sensor..I tested it vs old..

Old was good..

I retested iat sensor..this read different..I also found it changed as I moved it..

I took old coolant sensor and wired that to iat..

Wow things changed..isa motor freaked out clicking ..the plunger would jump but towards closed throttle..

Took for a ride..it now is driveable vs before..I will get ait sensor

It got up to 65 in 3rd..4th half throttle was best held 50 got 60 with 3quarter pedal..

Wot it bogged..5th bogged..

I know its timing advance and fuel..

The speed sensor I haven't touched yet..

Im also at 4000 ft above sea level..so thought that might another issue to a point

Okay, IAT does mess with air/fuel ratio, why do you want to mess with speed sensor?
