Here is a question.... My 90 gt auto has been running rough lately when first started. When it is first started it feels like it is missing. As the car warms up the missing subsides and you only feel it once in a blue moon. Not sure what is going on. Hopefully I can get some suggestions on what to look for. The car is fuel inject with 75mm tb,cai,bbk shorties and not to sure but I have an after market intake manifold also. All your suggestions are muchly appreciated....
