Van started to bog out and loose power as it worked its way to operation temp.
What is your question?
It has many miles and the motor is getting tired. Under power and in gear it started to fall on its nose, loose speed. In park or neutral you can throttle up and all. But under power and in gear you can not get over 2000 rpm and around 25-35 mph. Up hill maybe 10 mph. Thought maybe catalytic converter was plugged and drilled 3 holes in the side of the converter. It is doing better but only 10-20 %. The time from fine to only short runs ( less than 20 blocks or so ) was about 3 months. There was a slipping of the transmission prior to current state.
. Someone said it may be the coil packs too. I need better input I van not afford to take shots in the dark.
