Does my 2002 Chevy Impala have an idle speed control screw that I can raise my idle speed with


Well then you have a problem with the IAC - idle air control valve , air fuel mixture , mass air flow sensor , vacuum leak or some other problem with electronic fuel injection , OBD 2 ,emissions etc... There is an idle speed , minimal setting .Adjusting this will throw off the computer system , check engine light will come on an you won't be able get it to go out ! The PCM - engine computer controls the idle speed through the use of the IAC - motor or valve . Idle Air Control Valve You need to have it fix properly ! Check engine light on ?

I replaced my secondary air check valve on my 2001 chevy tahoe but code 1416 still comes up. what else can i check


here is what i found on p1416.



P1416 Chevrolet
P1416 Chevrolet - Secondary Air Injection System Bank 2
Possible causes
- Faulty Secondary Air Injection (AIR) pump
- Secondary Air Injection check valve bank 2
- Secondary Air Injection (AIR) pump electrical circuit fault
- Blocked Secondary Air Injection (AIR) system

When is the code detected?

The P1416 code is set when no O2 sensor voltage change is detected by the Engine Control Module (ECM).


Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)


P1416 Chevrolet Description
An Secondary Air Injection (AIR) pump is used on this vehicle to lower tail pipe emissions on start-up. The PCM supplies a ground to the AIR pump relay, which energizes the AIR pump. The Powertrain Control Module (PCM) monitors the HO2S voltages to diagnose the AIR system. During the AIR test the PCM activates the AIR pump during closed loop operation. When the AIR is activated, the PCM monitors the HO2S voltages and short term fuel trim values for both banks of the engine. If the AIR system is operating properly, the HO2S voltages should go low and the short term fuel trim should go high.

My 2004 Chevy Silverado can't pass the state inspection because every time I turn the truck off the memory resets, the same as if I would of disconnected the battery. I know this because I've checked it...


Have you checked B+ power feed for memory to the PCM ? The PCM/ECM - engine computer has a couple of power feeds and one is for the keep alive memory . Looking at a wiring diagram of the powers and grounds would show that . Testing with a volt meter would show if it has power or not . Check PCM B fuse 20 amp located in the under hood fuse box . An don't just look at it ,check for voltage across the fuse . This fuse should be hot at all times .

Change engine in different engine/350 fuel injection, try to find gas line to attach to switch with two tanks lines.


What you have is commonly known as a "dually" (because it has dual rear wheels) Essentially the truck is identical to others of that year except for the rear differential which has "floating" axles (likely a Dana unit). The best manual would be the original chevy shop manual...Otherwise try and find a chilton or motors manual for that year.
I don't quite understand what your question heading means...Are you considering swapping the engine?

My s10 will turn over, but wont squirt gas through injecter


Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's

I'd go with what emissionwiz said for the computer, a used one is a lot less than a new one. Also you can call summit and talk with their techs to determine which would be the best app.
