Rough Running Dually
So I've checked out some threads on here and have followed some advise....but I still need help.
My 91 TBI dually is running rough. It's worse when the weather is cold and especially at start up. Once warm it gets much better. I have not towed in some time but it also seemed to miss much worse when climbing. It would literally jerk from time to time.
Here is what I have done so far
New plugs, wires, cap and rotor
New fuel pumps and fuel filter
New map sensor
New temp sensor
Where should I go next? EGR, injectors, TB base gasket?
Thanks in advance for any time spent trying to help me resolve this issue.
BTW, check engine light is not coming on
