please help me im going crazy

[stevenSs]

ok so heres the deal i recently just swapped a new motor into my 2003 infiniti g35 rear wheel drive. i reset the tps and the computer as called for. but heres the thing at first i couldnt get the car to even stay idiling and now it kind of stays idiling but it has s***ty throttle response if none at all. car will not drive and is kinda lumpy. i checked each end of the connectors with a voltmeter and it shows the correct voltage. does anyone know what to do. i cant afford to take it to the dealer. please help me i just want to drive her again i miss her. i see the throttle body moving so i dont really think that its shot or the wiring is s***ty but im so lost PLEASE HELP

Do you have any codes?

Is it drive by wire?

Try this

From the FSM:

IDLE SPEED CHECK1. Run engine at about 2,000 rpm for about 2 minutes under no-load.2. Rev engine (2,000 to 3,000 rpm) two or three times under no-load, then run engine at idle speed for about1 minute.3. Check idle speed.OK or NGOK >> GO TO 10.NG >> GO TO 4.

4. PERFORM ACCELERATOR PEDAL RELEASED POSITION LEARNING1. Stop engine.2. Perform EC-668, "Accelerator Pedal Released Position Learning" .>> GO TO 5.

5. PERFORM THROTTLE VALVE CLOSED POSITION LEARNINGPerform EC-669, "Throttle Valve Closed Position Learning" .>> GO TO 6.

6. PERFORM IDLE AIR VOLUME LEARNINGPerform EC-669, "Idle Air Volume Learning" .Which is the result CMPLT or INCMP?CMPLT or INCMPCMPLT>> GO TO 7.INCMP >> 1. Follow the construction of “Idle Air Volume Learning”.

__________________________________________________ ______Accelerator Pedal Released Position Learning UBS0035CDESCRIPTION“Accelerator Pedal Released Position Learning” is an operation to learn the fully released position of the acceleratorpedal by monitoring the accelerator pedal position sensor output signal. It must be performed each timeharness connector of accelerator pedal position sensor or ECM is disconnected.OPERATION PROCEDURE1. Make sure that accelerator pedal is fully released.2. Turn ignition switch “ON” and wait at least 2 seconds.3. Turn ignition switch “OFF” wait at least 10 seconds.4. Turn ignition switch “ON” and wait at least 2 seconds.5. Turn ignition switch “OFF” wait at least 10 seconds.

Throttle Valve Closed Position Learning UBS0035DDESCRIPTION“Throttle Valve Closed Position Learning” is an operation to learn the fully closed position of the throttle valveby monitoring the throttle position sensor output signal. It must be performed each time harness connector ofelectric throttle control actuator or ECM is disconnected.OPERATION PROCEDURE1. Make sure that accelerator pedal is fully released.2. Turn ignition switch “ON”.3. Turn ignition switch “OFF” wait at least 10 seconds.Make sure that throttle valve moves during above 10 seconds by confirming the operating sound.

Idle Air Volume Learning UBS0035EDESCRIPTION“Idle Air Volume Learning” is an operation to learn the idle air volume that keeps each engine within the specificrange. It must be performed under any of the following conditions: Each time electric throttle control actuator or ECM is replaced. Idle speed or ignition timing is out of specification.PREPARATIONBefore performing “Idle Air Volume Learning”, make sure that all of the following conditions are satisfied.Learning will be cancelled if any of the following conditions are missed for even a moment. Battery voltage: More than 12.9V (At idle) Engine coolant temperature: 70 - 100°C (158 - 212°F) PNP switch: ON Electric load switch: OFF(Air conditioner, headlamp, rear window defogger)On vehicles equipped with daytime light systems, set lighting switch to the 1st position to lightonly small lamps. Steering wheel: Neutral (Straight-ahead position) Vehicle speed: Stopped Transmission: Warmed-upFor A/T models with CONSULT-II, drive vehicle until “FLUID TEMP SE” in “DATA MONITOR” mode of “A/T” system indicates less than 0.9V.For A/T models without CONSULT-II and M/T models, drive vehicle for 10 minutes.OPERATION PROCEDUREEC-670Without CONSULT-IINOTE: It is better to count the time accurately with a clock. It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuithas a malfunction.1. Perform EC-668, "Accelerator Pedal Released Position Learning" .2. Perform EC-669, "Throttle Valve Closed Position Learning" .3. Start engine and warm it up to normal operating temperature.4. Check that all items listed under the topic “PRE-CONDITIONING” (previously mentioned) are in goodorder.5. Turn ignition switch “OFF” and wait at least 10 seconds.6. Confirm that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.7. Repeat the following procedure quickly five times within 5 seconds.a. Fully depress the accelerator pedal.b. Fully release the accelerator pedal.8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stopsblinking and turned ON.9. Fully release the accelerator pedal within 3 seconds after the MIL goes off.10. Start engine and let it idle.11. Wait 20 seconds. 12. Rev up the engine two or three times and make sure that idle speed and ignition timing are within thespecifications.13. If idle speed and ignition timing are not within the specification, the result will be incomplete. In this case,find the cause of the problem by referring to the “DIAGNOSTIC PROCEDURE” below.DIAGNOSTIC PROCEDUREIf idle air volume learning cannot be performed successfully, proceed as follows:1. Check that throttle valve is fully closed.2. Check PCV valve operation.3. Check that downstream of throttle valve is free from air leakage.4. When the above three items check out OK, engine component parts and their installation conditionare questionable. Check and eliminate the cause of the problem.It is useful to perform EC-752, "TROUBLE DIAGNOSIS - SPECIFICATION VALUE" .5. If any of the following conditions occur after the engine has started, eliminate the cause of the problem and perform “Idle air volume learning” all over again:– Engine stalls.– Erroneous idle.ITEM SPECIFICATIONIdle speed M/T: 700±50 rpmA/T: 700±50 rpm (in “P” or “N” position)Ignition timing M/T: 15±5° BTDCA/T: 15±5° BTDC (in “P” or “N” position)SEC897C

Holy smoke! that is hard!

Holy smoke! that is hard!

Very hard! I think I might cover my eyes and sing a merry-go-round song What is going on with the car? Motor swap can mean lots of bad things. Something may have broken during replacement, motor may be from a slightly different model, etc...

i had tried resetting all those codes as i stated anyone have any advice please help i miss her

[G_whizz]

So you are getting codes or not?? If so, what are they??

[gwoods]

So you are getting codes or not?? If so, what are they??

what ar da codes

[stevenSs]

no i am not getting any codes at all.. and all the reset procedures that must be performed were done thats why im looking for any additional advice please help
