Looking for some advice. Car is a 97 cobra with a stock motor other than imrc deletes. Under acceleration, car hesitates and bucks. Fuel injectors are 2 years old, and using the screwdriver and stethoscope method i heard them all click. Fuel filter was replaced at the same time 2 years ago. Plugs and plug wires are brand new. No vacuum hose leaks. Premium gas. Compression test had 180psi give or take 2 in each cylinder. Problem gets worse if i put it in say third when i should be in 2nd and try wot. Stumped. Any ideas what it may be?
