hi, i just bought a 91 black fc convertible and I have to depress on the gas pedal all the way when the engine is cold to start it. And just recently, I had a hard time starting it when it was hot. Also, it idles rougly when its cold for the first few minutes. It is the original motor I believe with 153k miles. Thanks for your help

 

My first guess would be to get the injectors checked out. Anyone else wanna confirm?

 

Recently picked up an 89 vert. It ran rough until I got a tuneup.

Note the tuneup should help with the flooding, but it wont' solve it 100%. No big woop you just press the pedal to engage the fuel cut - then crank.

On the tuneup I had new sparkplugs, sparkplug wires, regular engine oil, coolant, synth in the trans, synth in the rear diff, etc..

Anything else??

Injectors, plugs, plug wires, TPS is what I would be looking at in that order.
