ok guys im here again with another probles..about a month ago a took my 05-AT 8 to the dealer and got a full tune-up ( coils, plugs, wire and oil changed)..now after i got the car from the dealer i drove it to my job. here is where i notice the problem accure. after i drove it to my job i let it sit about 10 mins and try to start it up, it took a while to turn over ( few cranks) i call the dealer back that same day they told me to let it **** and run for 20-25 mins. i did that now a few day ago i start it up it started fine, i went to put some gas in it after i finish i proceed to start the car up and the turn over problem accure againg...now i was wondering if it has anything to do with the gas filter? i was told there is two filter in the car. any help and advice will help.

 

A good place to start would be the battery. Clean all the connections and have the battery load tested. If that checks out, a compression test would be in order.

 

o i forgot to mension i did put a new battery in also..so i guess a compression test would be next..

 

ok i did a compression test today..it read F-180 R-150...now my question is what is the normal compression for the front and rear should be??...any info would help.

 

The compression has to be done with a Rotary Compression tester. It gives the compression of three sides of the two rotors and the RPM's it was tested at.

 

ok...but do you know what is the normal compression for both rotors? and at what rpm.
