Check Engine Light Stays on?

Is there a simple fix to this code or a general fix on Rangers with this code? I live in Germany and really don't have alot of resources.

The check engine light came on but the truck seemed to run ok untill yesterday. The battery was dead and it won't rev over 3000rpm while in park or neutral until you drive it, then it runs fine. Also the radio for some reason stopped working at the same time. I replaced the fuses and that didn't help. I am not sure what is related and whats not.

Did a complete tune up, plugs, wires, air filter, repaired all vacum leaks. Used a smoker to find leaks. Has high ltft on bank 1 at idle, 18%, other trims are normal, close to 0%, plus or minus 5%. On test drive it bog at full throttle and the check engine light flashes until you stop and let it idle for a few minutes. Engine don't seem to have full power. At idle it has a slight roughness. Think it may be cam positioner sensor. What do you think.

Thanks for the come back. I have a fully equiped functioning mechanic work shop. We buy it if need be and only rent if absolutely necessary, like a fork lift, etc.
We checked the fuel pressure yesterday along with what I said before. Just drove the truck and the check engine light comes on for a few seconds after you full accelerste. Pending codes are random misfire and miss on 4, 5, 6 cyls. Just checked the vacuum at idle and is around 18 inc. Now think the cat conv. Is spopped up on the right bank. Runs fine at low speed or low rpm's. Let me know what you think.

Thanks,
Jim

Fuel pressure is 58psi running and slow bleed of after shutdown. Seem to be a slight erratic reading on the b1 sensor 1 o2 sensor.
Just drove the truck again and don't have proper power and scanner reading was again, miss on 4, 5, 6 and random misfire but it runs perfect on the road as long as no full acceleration. Again the LTFT on bank 1 is much higher that the other ST and LT fuel trims. Yes we replaced all bad grommets including the drivers side pvc elbow. All with new parts. Tightened top manifold bolts. Drives like a restricted exhaust but who knows. Guess we will drill the 1/4'' holes in the exhaust tomorrow and see what the gauge reading is. Yes we are still open for other ideas, o2 sensor? Beats the hell out of me.

Thanks for the come back. This is fyi, believe it or not, our parts truck is a '97 3.0 ranger with 30 psi fuel pressure and 40psi if you remove the vacuum hose from the regulator. Has been running like that for about a year.
Remove the y exhaust pipe on the 03 ranger and the l side was partially blocked and the cat convs had come apart. Has three cats on that pipe and all were bad. Will replace the y pipe with factory type.

Thanks

Truck runs pretty rough at times I plugged in my code reader and reads out 0303 which is #3 cyl. Misfire detected. Could this be a bad coil? Is there a simple way to check this? Thanks

I have 2 codes, on eof them is P2196 Lack of HO2S-21 Switching, Sensor Indicates Rich. What would cause this problem. I have replaced my 02 sensor twice as well as the ICM. Also I have a P0132 HO2S-11 (Bank 1 Sensor 1) Circuit High Input. What is this problem. I have had it to the dealer more than once

It is a 4.0L

The engine lite does not come on but the car seems to be getting hot icould it be a problem with the fuse where can I find the fuse for the check engine lite I do not like driving without it working

Is there not a fuse the light never lights up on most cars it lights up when you start it and then goes off this one never lights up
