How would you know it lacks power in the first 20 seconds?
Do you skip the warm up step and aggressively drive the vehicle right away? (that's very bad and not very bright if you do)
In what way is power lacking?
What was the temperature outside?
ATX or MTX?
How many miles?
What year? (I'd guess 95 since you are describing OBD-I steps???)
What engine?
What have you checked?
