I have replaced my tps sensor, cleaned the throttle boy chamber,

Customer Question
had all plugs, wires, cap...
I have replaced my tps sensor, cleaned the throttle boy chamber, had all plugs, wires, cap, rotor, & valve cover gasket replaced. Along with cam & crank sensor. Since then every time you start car it starts around 3,000 rpm after 8-10 min drops to 1,500 & after few more min goes to normal. If you don't it feels like the engine is going to jump through the dash board
JA: Sometimes things that you think will be really complicated end up being easy to fix with a Nissan. The Nissan Mechanic I'm going to connect you with knows all the tricks and shortcuts. Are you hoping to fix this yourself?
Customer: This si also the 2nd tps sensor I had installed the 1st made rpms jump from 1.5-2.5 just going 20mph, Nissan said I hay have defective one again
JA: Is there anything else the Nissan Mechanic should be aware of about your Nissan?
Customer: just that I am spectical on trusting anyone, with the suspension work I did was over $2k & now car sruns worse than before
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Nissan Mechanic about your situation and then connect you two.

Now every time it shifts from 1st to 2nd & 2nd to 3rd it shifts hard. Like the timing is off. i have relearned the idle severaltimes. Recently it is misfiring more 7 more, stalling & shuttering even while driving
Customer reply replied 1 year ago
I thought it was possible for a 2nd bad tps sensor. But now am thinking possible idle air control vale or the speed sensor, as recently neither of my radiator fans are working? So as well as running terrible it is running HOT & wants to overheat! PLEASE HELP
Customer reply replied 1 year ago
Thought you should know it is a 2000 Nissan Altima GXE with 233,000 miles.

Also I was directed to your site for location of IACV, then an instant chat came on & I even elected to the Premium Service of $50.00 after 7 day free trial to get unlimited answers & response within 5 minutes?
I am at work now but will respond within minutes of you responding to me..... I need this car to run right & not over heat. I thought I was doing right by putting $2,000 into it not including tires & alignment.

Customer reply replied 1 year ago
again I am at work & cannot call can type
Customer reply replied 1 year ago
So? my car NEVER shifted hard or ran at such high rpms. Do you think I am right on the idle air control valve, I thought it was speed sensor but was unsure. Also can the speed sensor cause no fans to run w/ my radiator fans? It was working fine & even had AC, now does not have any AC, the light o the button on the dash don't even come on. I do have heat & it blows out fine & all of my relays are good. Thought was fan motor, it just does NOT come on at all. But then read speed sensors if malfunctioning can cause fan motor to not work
Customer reply replied 1 year ago
Are you there? Please I have waited almost 2 hours for a response & a call does not work for me today. The chat person chatted with me 1st & no one has really responded at all???

Hello the TPS codes are P0120, P1705 & P1705 not sure why it had the last one twice? Also since installing new TPS the OD light blinks 16 times every time I start the car, mechanic told me to not worry about that, why after searching had me thinking it was speed sensor. Along with my fans no longer working at all.
Nissan Mechanic: Ron, ASE Certified Technician replied 1 year ago
Both of these codes can be set due to any of the following, Idle SwitchThrottle Position SensorThrottle Position Sensor (TPS)Throttle Position Sensor (TPS) AdjustmentIn order to determine the cause you are going to need to do some testing.

Customer reply replied 1 year ago
Ok I will thanks and the "mechanic" I took it to that fixed this told me the TPS cannot be adjusted. Am I correct in thinking he's been wrong all along? And would the tps error cause the OD light to blink 16 times when it starts?
Nissan Mechanic: Ron, ASE Certified Technician replied 1 year ago
It can ba adjust by changing the throttle hard stop. The OD light blink is not likely related to the TP codes and or concern.
