I have a 94 pickup w/22RE in it. When the motor is warm, it will miss our stumble when taking off. The Missing is usually from 1st gear to 2nd and 2nd to 3rd. Ive changed the EGR Valve, Air filter, Exhaust Manifold, New CaTT, Spark Plugs&Wires. In January it started tapping and missing due to 0 compression in #1 cylinder and #4 Missing. I got the motor put on a machine and replaced piston rings. It ran fine for a week and started missing again and the check engine light returned throwing OBD1 code 25 (running Lean)
Any suggestions on what i should do next?

 

injectors...

 

no worries now, ive ordered a 22re Stage 2.5 from Putney's 22RE Performance w/forged pistons, ports polished, dual row timing chain, larger valves and springs ect., high boost turbo kit from LCEngineering and SDS fuel management system also from LC. I cant wait to get the parts in to start this project. pic's coming soon.
