4 fuel injectors on drivers side on 2002 chevy tahoe are failing. Can I get replacements from newer models?

injectors sometimes change from year to year so you need to find out what years are inter changeable with your truck and engine can ask the wreckers,the dealer or the parts stores.are they failing because of an electrical problem or because of a dirt problem.if its a dirt problem why not have the fuel system/injectors serviced to be cleaned.this may fix it and is cheaper than replacing injectors.if its electrical then replacement is the way to go.

My 2002 tahoe rpms jump up when I first start in the cold. Motor has slight lope in it until warmed up. why is this happening

Try cleaning your maf (mass air flow sensor) with maf cleaning spray and also checking or replacing your air filter if needed. These vehicles also have a cold start fuel injection system which is supposed to regulate the engine speed/idling until the vehicle has reached operating temp. You may need to get a professional fuel injector treatment which is much better than the bottle in the gas tank remedies which seldom do more than waste your money. I personally use a bottle of iso heet fuel additive when I fill up every 4 or 5 tanks this helps to remove any moisture which may be present in your fuel. I also recommend purchasing fuel without ethanol, it degrades the octane levels in your fuel and can cause reduced performance and build up on your intake valves.

2002 Chevy tahoe won't start turns over but won't start

Most common problem is low or no fuel pressure. You will need to get a fuel pressure reading and post back.
If there is no or low fuel pressure then most likly the fuel pump is bad and needs to be replaced.

2002 Chevy Tahoe sputters like it's not getting gas and stalls out while driving. usually starts back up after a few min. mostly only does this when it's hot out

Hello , does the vehical stall out after its been driving a while and the engine has reached operating temp? It may be what's called " vapor" lock. This is where the fuel is burned or evaporated in the fuel lines and the result is not enough fuel is routed to the injector system. Or you have a failing fuel psi regulator too. Thank you , Quinn
