My intentions were to simply replace my valve cover gasket and the cap/rotor. Now the car stalls at low speeds 20-30 mph. I also treated the intake with seafoam motor treatment. Thinking it may have clogged the converter, I removed it, and was able to see through it, so I reinstalled it. I looked for cracked lines and repaired a couple. I tried the spraying water trick on the coil and distributor area. I disconnected several electrical connectors and treated them with isopropyl. I sprayed carb cleaner to look for vacuum leaks. When it stalls, if I keep pressing the gas the car will die, as soon as I let go of it and press in the clutch, the car will idle. I double checked the dist cap installation and firing order too. Any ideas?
