V 10 EXCURSION FAILING EMMISSION AND HESTITATING hc 580 SHOULD BE 300 NO ENGINE CODES

run fault codes
indicate ambient temp sensor , maf,vaf or engine coolant temp sensor problems

You should check out www.reliable-store.com they have info on repair, service, wiring diagram, electrical diagram, fuse diagram, torque specs,
troubleshooting, PCV, gear box, owner's/service/repair/parts manual, fault codes, error codes, etc everything on all vehicles. must check it out

if it is an EFI engine then the parts that you will need for a tune up will be indicated in the fault codes
The ECM of the vehicle continually tunes the engine while running ( around 100 times a minute) and as long as all the sensors are within parameters ,the engine will remain in tune
any sensors that are failing will leave a fault code and just because the engine light is not on doesn't mean that there are no fault codes recorded
basically "good mechanics do not fix what isn't broken"

HC is raw or un burnt fuel. CO is incomplete combustion meaning the air fuel is burnt but not burnt completely. check O2 sensors for operation, fuel pressure, gas in oil or how long has it been since an oil change. check engine timing, dirty injectors. when was the last time a tune-up was done plug/wire condition is the air filter clean. just some things to check

fuel pressure should be 34 - 38 psi.fuel pump could be failing.

what are the codes saying? PCM Codes? Emmission Codes? misfire codes?

You'll have to get the codes read and fix the problem. Take it to a place like Auto Zone, they'll read the codes for you. Hope this helps.

P1132 is front 02 bank 1 and P1152 is front 02 bank 2
This codes indicate a rich condition. I would check for a dirty air filter or a dirty MAF sensor.

The easiest way to find out what the code stands for is to call a near by AutoZone store. Tell them what year, make, model and engine you have. ask them if they can tell you what the code means.

Have you got all your hoses running to the emmission control box (usually a round or rectangular box on the passenger side near firewall). Is the box old and needs replaceing? If you don't want to change because is very dear to do you could change your spark plugs and fuel filters? Also change your oil with a lighter oil a 55w/10 and oil filter and your spark plug leads with new ones 8mm diamiter would be good as it is less resistance for the spark which will aid in fuel burn and air filter change is good idea to, maybe 200 dollars or so to do this but all will help reduce your emmissions if emmission box isn't working properly. Hope this helps
