I have an 89 vert' with a SETA plant in it. it has been doing some weird stuff, but its hard to describe.
if I punch the throttle when the engine is cold, the power just dies. nothing, no spark, no fuel, no power... until I lift off the gas. if I accelerate gently when the motor is cold (less than 1/2 throttle) then its pretty symptom free.
when it warms up a little more, I can flog it, pulls fine until 3,000 rpm when it just sits at 3,000rpm throttle maxed, but the exhaust note sounds soooo weird while it does it, a louder, more open tone? not sure at all what that means. it will eventually stutter past 3,000 and pull hard to 5,500rpm.
also, the car is sometimes EXTREMELY hard to start. It may take 15 seconds of cranking and throttle pressing to get it to cough, and some times, I just touch the key and it pops right into life.
I just swapped the fuel pump and the coil, exactly the same.
any ideas? this is my tow car so I need my boot in it all the way often and this is annoying.
thank you much!
