Hi guys,
I dropped a 302 efi from a 91 in my 68 mustang, put a tanks fuel tank with intank fuel pump. Fuel pressures holds steady at 40psi. When i drive the car it bucks and feels like it has no power. The car also idles rough and fluctuates. Ive checked the firing order and its right. Please give me some advise on how and where to start. Everything is stock, thanks. When I bought donor car it drove fine. Took out the 302 and rebuilt it with a ford tech (friend which is always busy). I dropped the engine in my. 68 and drove good and strong with an occasional sputter or hiccup. The sputter became more and more. I changed the fuel system to a Tanks inc setup. Fuel pressure stays at 40 psi. I disconnected the tps and drove it around the block and stilled bucked. I disconnected the mass air flow sensor and drove it and still did the same. I did transfer the map sensor too. My wiring harness is custom rjm harness so it's not rigged. The car idles like s**t. What else should I diagnose? It also smells rich
