1st gen injectors

Thanks for all of your help if anyone else knows what parts will interchange please let me know

 

I would try to find out a bit more about the motor you have. They should have a serial number (not a VIN) on them at least- might be able to pin down what year it is at least.

I'd call a shop- something like LCE or YotaShop. They might be able to give you more specific year-to-year details than the collective group here.

 

It will run decent some times, it does the best first thing in the morning when it’s cool outside. But it still feels weak and ideals up and down.

then if I leave it in the sun when it’s 90+ degrees outside it won’t idel at all and I have to hold the gas pedal to the floor to get it to crank and keep the rpm’s up a little bit when I put it in drive or it goes dead

 

Also my rpm gauge reads low. Say if the truck is running 2 rpm’s the gauge reads just a little over two

 

And also where would the serial number be located on the motor?
