93 explorer xl 5speed
So i have a 93 explorer xl 4wd 4.0 5speed and its giving my some engine trouble. Here's what its doing.... So when its starts it spikes to 2500 rpms then drops to 1000 then it continues to spike like that even while driving also when in idle and it spikes you can hear it backfire in the air filter chamber. I have replace the maf, iac, tps, and throttle body. I also currently have two recent codes and they are 211 and 214. 211 is a profile ignition pick-up circuit fault. 214 is a cylinder identification circuit failure. Plz any help is greatly appreciated
 






code 214 Error in Cylinder ID (CID) circuit or signal

This relates to the Camshaft Synchronizer located at the rear - top of the engine block and below the intake. I have replaced mine and it is not a job for a novice mechanic as it is difficult to access and requires careful alignment. There are online guides and an alignment tool for this.

Code 211 Ignition PIP signal was erratic or missing

I believe this relates to the Ignition Control Module but may have other causes. Others should chime in on this one
 






Thank you very much for the info
