..my car was running perfect with no lights and codes...it was time for a tuneup so i started with looking to see if the throttle body was dirty..it was alittle so i sprayed some throttle body cleaner in there let it soak for 1 min,sprayed alittle more and all looking very clean so i buttoned hear up waited an hour and started her..it now runs rough and has a red light with limited performance on the dash...pulled codes(high end reader) and got p1226 and a description..does that mean a very small amount of throttle body cleaner ruined my throttle body and now i need a new one????

 

The P1226 is an unusual code that apparently applies only to early, '96-'98 cars and is associated with the Throttle Body.

Try a hard reset and see if it clears.

The mechanical guard is explained in this document:http://www.thejagwrangler.com/upload...c_throttle.pdf

 

As has already been stated, code P1226 applies only to early XK8's. Here is the list of possible causes (see middle column):



It's some coincidence to develop a harness or sensor fault just after cleaning the TB. Assuming no physical damage to the guard spring during cleaning, probably you've been a bit over enthusiastic with spraying the cleaner.

A hard reset may clear the code. If not it will have to be cleared with a scantool.

well i got the code to go away..i removed the intake tubing,inspected for leaks,found none and its in really good shape.reassembled everything and codes went away..but she is idleing very rough at idle..anything over idle its smooth as can be and has great power but idle is very rough..thoughts?

 

Have you cleaned your Part Load Breather orifice?
