A miss
I have a 2000, just had the injector pump and lift pump replaced. It's developed a miss of some sort. Idles rough and tends to be worse when it's at operating temperature. Runs down the road great, just rough at idle. The mechanic that replaced the pumps said his computer couldn't pick anything up on a possible injector problem and no codes on the pump. Attempted to crack each line individually and still couldn't make a determination.
Any ideas?
