i have a 1994 5.0 cobra. now it starts perfect and runs strong for about ten mins( long enough to get to full temp) and then it starts to knock and the speedo twitches and the car stutters. its a random thing but starts around 2000rpms . you can feel it getting stronger over time . now i have changed cap, rotor, wires plugs . cleaned the MAF and the throttle body . a friend says injectors . id really be gratful for any input

could be the injectors like your buddy said. I had a similar problem with my beater (94 tempo gl 2.3l) we think its the injector leaking sending in more gas then needed. but mine starts like that then it gets better over time

It sounds electrical to me like a TFI module or a PIP sensor since it starts to act up once the engine is warmed up. Electrical components can act fine when they are cold but once they start to get hot they will begin to give up the ghost.

well i changed the injectors and as i was putting everything back and i noticed the pipe that goes down from the egr valve is busted . i drove it and the problem was still there . my next question is to delete the egr valve what else do i need to do ?
