Question about 2002 Jeep Wrangler
2002 Wrangler 4.0L, swapped engine with a new Titan 4.6L Stroker.
New cam and crank sensors, 4 new o2 sensors, new 24lb injectors, new 62 mm throttle body, new Banks Headers, K&N cold air intake, new ignition coil, new map sensor, new throttle positioning sensor. 3 new "cats".
Engine will start with a flick of the key,and idle all day......once you try to add a little throttle,the engine will die.
Borrowed a computer from another 02 Wrangler, same problem.
Cleared all ''codes'' on the computer. Checked and rechecked all grounds. Fuel pump is putting out 46 pounds.
I do however think this is a problem with the ''computer'' not being able to ''read'' the new, more powerful engine.
Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
