Rough Idle & Poor gas milage 94 B3000
Hello I am new to the forum and could really use some help.
I have a 94 Mazda B3000 Automatic with 180,000 miles. Recently had a problem with error code 327 and fixed that with a new EGR sensor. Code went away but the truck idles very rough and gets 13 mpg. Also it smoothes out a bit when driving until I get into overdrive and the RPM goes below 2000 and it gets worse.
I cleaned the EGR valve and checked that it is opening at about 9 to 10 psi.
Can anybody shed some light or point me in a direction?
Thanks
