Why is it hard to Start when Cold

[LuluBelle]

New TPS Arrived I wish I could say that's it...... Fixed thread Closed....
BUT!.....
It's still not 100%...........
It starts up fine runs smooth-ish at idle .. check engine light goes OFF! When you drive it now it's smoother But Gutless Like its clogged up? It's Not the Cat! New exhaust 2 yrs ago under 5000k .....
Does anyone know any thing about the EGR valve?......
I ask this as when I fitted the PCM I got codes 32 egr valve and 22 the new tps fixed that one I looked up the egr stuff and its confusing for xj owners or is it Me?
Could not find one on rockauto only the gasket can you clean it? I will have another look online and tomorrow I will check for codes and look at the vac hoses at the moment I have No Idea But! it Runs and is Driveable....

If the EGR valve hasn't been cleaned/decarbonised in a while it might look like this:

I don't even think XJ's have a EGR now ....?
But there is the Emission Control Canister Purge Solenoid this is so confusing ...But can effect the fuel Air Ratio....
and is controlled by the PCM which probably fried it when it died Getting Closer I might get one and try it

The xj diesels have EGR.
How is the air filter?

Emission Control Canister Purge Solenoid
Symptoms of a Bad or Failing Canister Purge Solenoid

•Rough idle. One of the first symptoms that a faulty canister purge valve may produce is a rough idle. ...
•Difficulty starting. Another symptom commonly associated with a bad canister purge solenoid is difficult starting. ...
•Check Engine Light comes on. A defective canister purge solenoid may also set off the Check Engine Light.

Usually, a bad purge solenoid will display any of the following 5 symptoms that can alert the driver of a potential problem in need of servicing.

•Rough Idle. ...
•Poor Engine Performance. ...
•Difficulty Starting. ...
•Check Engine Light Comes On. ...
•Low Fuel Economy.

If your canister purge valve is stuck open, however, it creates a vacuum leak that can affect your engine adversely. Simply put, air will be allowed to enter the engine in a quantity that is not predicted by your car’s computer. This will change the car’s air to fuel ratio, and can cause rough idling (car feels rough and bouncy when the engine is running), as well as difficulty starting. If experienced in tandem, there is a high likelihood of a failing canister valve, or some other part of the EVAP system.

The more I google I think this might be the issue
I think when the PCM committed suicide it tried to take a few of its servants with it to the after life ... Back to waiting on rockauto & FedEx

I cant work out what item is the one you are changing?

imo, an OBD2 reader would help you a lot, if I understand correct,
ur relying upon the key jig?

my old corded one works, but the new bluetooth one doesnt
(on my 2 early 96)

an old style obd2 reader should be like $5 on ebay ?
