Engine Performance problem
1994 Ford Explorer 4 cyl Four Wheel Drive Automatic 190000 miles
1994 Explorer, 4.0 liter: I want to check the vacuum motor, etc for the air intake. It's located under the battery case. Do I access it via the wheel well?
It runs rough when first started and then fine after driving for about 15 min. I did get a code 327 (egr) and I've
replaced the pressure sensor and the egr valve. Got rid of
the code but doesn't run any better. Started thinking that maybe it needs heated air at startup and isn't getting it. What do you think? (Also replaced fuel filter, air filter, plugs & wires. Passed cyl bal test. No nasty signs
from spark plugs nor exhaust.)
