timing and backfiring issues, please help!
My 89 3vze is having problems that I am just stumped on...
The problem I am having is that..
1. I CANNOT get my timing right. I have checked and had other people double check my work on timing belt alignment. the truck runs, however when I try to time it with the timing light the closest I can get is 5 degrees BTDC or 19 BTDC by moving the distributor 1 tooth either direction.
2. When running it wants to back fire up the intake. It has no power when driving
Soo with that said here is what I know.. New fuel pump, TPS is working correct, MAF is working correct. There is NO CEL codes.. not one ever and the light works. Cylinder compression is between 175-182 for all.
Any help would be greatly appreciated so I can have a vehicle running.

How long was it running and driving fine? If you put all new hoses on there then maybe one developed a crack in it. They don't make stuff like they used to is a saying for a reason. You can spray carb cleaner around your hoses and listen for the engine to race. I don't know much about the 3.0's but on the 22re. Even a very small vacuum leak will cause strange issues. Good luck keep us posted.
