When accelerate my 1999 gmc jimmy pops


Multiple failures will contribute to this symptom. Both mechanical and electrical issues need to be looked at. Check for "Engine light" and any active or stored engine codes. Running a cylinder compression test, fuel line pressure test, exhaust pressure test, check the timing, check for misfire, check for clogged fuel and air filter, defective MAF or MAP sensor, check for vacuum leaks. The more details you can provide. I may be able to help you more.

What does this code mean? P0410


Diagnostic Test Code (DTC) P0410 indicates that your secondary air injection system is not functioning properly.
Not all 2001 Chevrolet Bazers are equipped with secondary air injection. The secondary air injection system was added to vehicles that were to be sold in certain areas where the emissions laws required it, like the State Of California.

The Powertrain Control Module (PCM) monitors the system by commanding the secondary air blower motor to run and the air injection solenoid to open. This causes additional oxygen to enter the exhaust system. The PCM then monitors the signal from the oxygen sensors to see if the commanded air has in fact, entered the exhaust system. Code P0410 sets when the PCM has commanded the blower motor on and the solenoid open and there is little or no change in the oxygen sensor signal.

GM has had some problems with these systems and there has been a Technical Service Bulletin (TSB) issued that addresses some of the known concers. Below is a brief description of the TSB and the issues involved.

Bulletin No.: 04-06-04-015A
Date: November 28, 2006
TECHNICAL
Subject:
LN2, L43 or L35 Engine SES/MIL Light Illuminated, AIR Pump Ingesting Water and DTC P0410 Set (Replace AIR Pump and Inlet Hose Assembly)
Models:
1999-2003 Chevrolet Blazer, S10
1999-2001 GMC Jimmy
1999-2003 GMC Sonoma
1999-2001 Oldsmobile Bravada
with Vortec 2.2L I4 or 4.3L V6 Engine (VINs 4, 5, W - RPOs LN2, L43, L35)
Condition
Some customers may comment on the SES/MIL light being illuminated. Upon investigation, the technician may find a DTC P0410 indicating that there is a concern in the secondary air injection system.
Cause
Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump.
Correction
Replace the AIR pump and install a new inlet hose and solenoid tube assembly...

The bulletin goes on and gives detailed information on how to perform the repair and the part numbers of the replacement parts needed to do so. Your local dealer can provide the parts for you and you can probably get them to print out a complete copy of the bulletin for you. It is not really hard to do if you want to do this yourself.

The machine it talking about code P1345 CKP/CMP sensor correlition Do the engines RPMS fluctuate at idle or if you try to hold it at a steady speed if so then check the connection at the CKP make sure it is getting voltage its installed correctly and so on.

I have a 2000 2.2L Sonoma that I had to replace the motor in with a 99 engine and when I did the exhaust manifold was different and I could not hook up my air pump and I now have a service engine light on all the time but it runs just fine and I even think it improved my gas mileage. You might check your air pump connections or sensor. The air pump is on the front of the engine below the ac unit. I TOO have a Hanes book but also a Chilton book because 1 covers some things the other does not
