Well, I'm new to the game and would like to get my Z running right. I purchased the car 4 years ago and sat on my garage for that same time, up until now that I sold my Evo and opted to run this beauty.
I have changed the spark plugs, wires,rotor and cap, fuel filter, pump, afm that I've purchased from a member here, coolant sensor, cleaned connectors and God knows what else... Now the issue is that a month ago the car ran "fine" with the previous afm and fuel pump, but had done the regular tune up parts. After driving the car for a couple of days, one night the car started to sputter and while giving it gas, the car wouldnt rev and simply fall flat and die. Startup got hard after operating temperature was reached and from there it will have a hard time reving passed 1200 rpm and on, but will idle fine. Now.if I let the car sit and cool down, the car will start up fine, idle fine and rev up high when I open the throttle, but when it warms up, I close the hood and I try to drive away, the car would no go passed the 1200 rpm and continue to drop until it stalls.
I have Disconected the TPS and reconnect and appears to somewhat work for a couple of seconds/min. And then go back the faulty stage. Could the tps cause this condition? Any ideas of what could I check next to get it running like a champ?
Forgot to mention that engine was rebuilt by PO.
