My fuel filter was so tight I couldn't blow through it. I replaced it no problem. I'm getting a shudder when it lugs down in OD and it's lunging in drive when driving easy. If I accelerate it shifts better but not very firm. Yesterday driving home I had to stop hard for a light and it died but restarted right away. I have replaced the water temp sensor and cleaned the IAC. This rig has been sitting some and I have only ran one tank of fuel through it. 75,000 miles. I put some enzyme and some heat in the fuel because I suspected it may have had some moisture in the fuel. Where do I start checking? I want to check the fuel pressure but don't have a proper gauge. Should I buy one? I also think I need to pull the transmission pan and look around. Any and all help is appreciated. Sunfish
