I have a 74 2.0
Idle stays low (verge of stalling) and Idle screw has no effect.. Jump on the throttle a few times and the Idle stays High.. Turn it off and restart the Idle is low again.. What is the vaccum supposed to be in the system? I reset the timing and that helped a little. Idle is steady. Is my TPS mal Adjusted. Wher and how to I start to search for what is wrong? After 2500 rpm the car runs and climbs but try to hold at 2500 rpm in the driveway and the rpm starts to drop slowly.. Things I recently changed.. New control NOS unit (matches the car year and the mps) New Vacumm Hoses and Fuel Lines.. New Cylinder Heads (valves etc.) 3 New Engine Harnesses (Ignition, Alternator and FI) New Cold Start Vlave New temp 1 and temp 2 sensors.. Had Serviced the Injectors too ** I DiD change the New decel valve hose routing to Match what is discussed in THE ECU link which differs from pelican parts.. ANy help is goo help.. |

I would check to make sure you have the correct CHTC on the passenger side head!
Also check the threads....mine were stripped when I bought the car and it took me two weeks of trial and error to figure out that the CHTC was not making good contact with the head. |
