Heavy Flooding 2 Cylinders (2,4)

[im2345solie]

My '92 paseo had an intermittent problem of rough running during acceleration that would typically go away if I engaged the clutch and released it.

Now it is not so intermittent.

Now it will start but it pumps so much fuel into cylinder 2 and 4 that fuel actually leaks out where the exhaust manifold connects to the exhaust pipe and drips onto the ground. The plug and cylinder look very wet on the 2 cylinders and dry and normal on the other 2. I have good spark on all cylinders and the resistance of the FI is within spec. If I disconnect the FI connector the cylinder and spark plug dries out, but when I reconnect it the same flooding occurs. No check engine light. I have replaced the fuel pressure regulator and sparkplugs.

Has anyone seen this type of problem?

My next step is to either put a scope on the injector control wires, or to swap an injector from a flooding cylinder to a non-flooding one.

possibly check your ignition coil. take it to an autozone. maybe checker, kragen, ext might be able to test it for free too. but i know autozone does test it for free.
