car dogging up hill or after running for 30 min.
Why does the car bore down an a hill or after it has been running for at least 30
min. The dio. test shows map sensor. Put new one in, still does the same
thing. Any ideas what to try next??
It could be the Ignition Coil. My '02 PT would run ok for awhile and then start missing. Replaced Ignition Coil and it ran correctly. Note: First replacement I bought a cheap Coil on Ebay and it only ran for a month or so. Put in a better part and no problems since.
