Surge at low speed
a little info vehicle is a XJS 2+2 4.0 US specs automatic trans
I had a code that EGR valve was bad checked with vacuum pump it was
replaced with new valve Run good with new valve
But after a few miles the vehicle has a surge at low speed with light throttle speed below 10 MPH .very light surge when warm . Runs very well at high way speeds and also speeds above 10MPH .
If I disconnect hose to EGR valve and plug hose NO SURGE
Anyone have the same trouble?
