Does the engine still have a misfire? What was the code number you were getting previously?
OK thanks. I wonder if we have a bad coil on cylinder 5. That is the first front coil on the driver side. Make sure we have no oil getting onto the coil boot. I then recommend we disconnect the negative battery terminal cable for about 30 minutes to reset the ECM. Then take it for a drive in sport mode and see if it will accelerate.
Figure we should see about 35 psi. Could be a transmission issue which is why I recommend sport mode. Let me know.
OK still may be a transmission problem. First check the throttle cable to.make sure it is not stretched. Then also check the intake air rubes to make sure they are not leaking.
You may be able to get slight movement from the pipe as there is a rubber seal that should be on the throttle. That pipe is held in by the two 8mm bolts. For the transmission it could be electrical but usually if a solenoid or regulator was bad you would get a gear box fault warning. We should check the fluid level and condition. Since there is no dipstick this is not easily done. There is a fill/level check plug that needs to be removed with the fluid warmed to temp, engine running and vehicle on a level surface or lift. Once fluid flows out it is full.
I would at least check the level and condition.
It is the 8mm allen/hex fill plug on the side of the case. We are looking for a steady small stream of fluid with the engine running, fluid warmed and vehicle level. We are looking to see if it is full and not burnt or having debris.
Does it accelerate if you use the manual side of the shifter?
OK. Let me know.
On then this could either be a problem with the transmission control module or the transmission itself. Unfortunately it will be difficult to diagnose without a Jag factory tool to read the TCM.
