My car is running really bad,( I would push my gas pedall and the car will wait a couple of seconds and then go, CEL is on, I did clear it, found one of my vacume lines was off for the nos system, put it back on, CEL came back on) I got 98 SE with a V6, I got SVT TB and UIM. Rest is SE parts, on the OBD II code comes up as IMRC MALF code number 1518. All the help will be great.
Thanks Sergey.

The following is from the Ford TSP (Technical Service Publication):


DTCs P1518, P1537 and P1538 indicate IMRC may be stuck open. DTCs P1512, P1513 and P1519 indicate IMRC may be stuck closed. DTCs P1516 and P1517 indicate IMRC input error. DTC P1520 indicates IMRC control circuit malfunction.

Possible causes:
-- Cables improperly routed (binding) or seized.
-- Damaged/disconnected IMRC housing return springs.
-- Lever/shaft return stop obstructed/bent.
-- Lever/shaft wide open stop obstructed/bent.
-- IMRC lever/shaft stick/bind or disconnected.
-- IMRC actuator cable/gears seized.

* View cable routing. Make sure cables are not binding or improperly routed. For vacuum operated IMRC systems, make sure sensor linkage is attached and secure. Also, make sure IMRC sensor harness connectors are attached to the proper bank. They are interchangeable. If necessary, use a breakout box to pin out the harness connectors to the corresponding electronic EC pin. With engine off or at idle, cable core wire at IMRC housing attachment should have slack and lever should contact Closed Plate Stop Screw.

* Manually open and close IMRC plates at intake manifold, feel for sticking/binding.

NOTE:
IMRC return spring is strong. Make sure return springs operate properly and plates open and close fully.
