Misfire?

When starting from a dead stop car feels like it has no power (misfire) but when it gets higher in the rpms it runs fine. Only does sometimes and only after starting the car. Any ideS?

Do you mean a hard start from a stop? Heavy acceleration?

Try cleaning the MAF if thats what you meant. MAF cleaner spray only.

Clean the MAF and make sure the intake elbow is firmly seated on the TBI. I had a problem with mine not wanting to go and the elbow had come loose from the TBI.
