Question about 2008 Chevrolet Hhr

1 Answer

What could be the problem with a hard starting after an ultrasonic injectors cleaning?

Hi I have an HHR 2008, I did an ultrasonic cleaning on Injectors, after that I have a hard starting, but the think is that in the first try in the morning everything is ok, even when I just turned off the motor and try again, it works, but after like 15 minutes or more if I try the HHR has a hard starting of like 5 or 6 seconds.

SOURCE: How to replace the fuel injectors on a 2002 Tahoe?

To Install:

  1. Lubricate the NEW fuel injector O-rings with clean engine oil.
  2. Install the O-rings on the fuel injector.
  3. Install a NEW retainer clip on the fuel injector.
  4. Install the fuel injector in the injector socket with the electrical connector facing outward. The retainer clip locks onto a flange at the fuel rail injector socket.
  5. Install the fuel rail.
NOTE: Use care in removing the fuel injectors in order to prevent damage to the electrical connector pins on the injector and to prevent damage to the nozzle. Service the fuel injector as a complete assembly only. The fuel injector is an electrical component. DO NOT immerse the fuel injector in any type of cleaner.

I had the exact same problem with mine. After replacing nearly everything i took it to a shop today to learn that I had a bad wire on the back of the distributor and the new fuel pump i installed from autozone was faulty and not providing enough pressure.

I have a 2008 chevy hhr, starts fine and idles


Have you replaced the spark plugs or coil packs? A lot of times spark plugs will only miss once a load is put on them. Here are some tips to help you narrow it down. All you need is a screw driver and a code reader.
First, is your check engine light on?

----> if yes, try to get the code it is throwing

is the code current?

----> if no
1. Pop the hood
2. Remove the air filter box cover and inspect the filter
---> is the air filter clean?
If no, replace the air filter
If yes, remove the engine cover -

3. Find the fuel rail located toward the back of the engine bay and find all 4 injectors.
Place your thumb over the end of a long flat blade screw driver, place it carefully on each injector, and place your thumb on your ear. With the engine running, listen for fires from the injector
-----> are all 4 injectors firing rapidly at the same rate?
----> if yes, start with replacing all 4 spark plugs
----> if no, replace the fuel injector that is not firing

If yes ---> is the code for an engine misfire?

See above instructions

if no ----> is the code for throttle body position?

if yes ---> Replace the throttle body position sensor and perform the relearn process via tech II scan tool.

These are the most common issues with misfiring with engines, hope it helps or leads you in the right direction.

Hard start runs rough floods bad


Well--I usually would say do some testing

BUT- on a 23 year old vehicle--I would mail away
the injectors & have then tested & Ultrasonically
Cleaned

Then install new spark plugs

Next check fuel pressure

New oxygen sensors-again- I assume nothing has
or is every been done to it

Clean the MAF Sensor & check for Vacuum leaks

Code p1349 in toyota echo 2004


Under certain conditions customers may experience a MIL "ON" condition with DTC P1349 indicating a variable valve timing (VVTi) malfunction. In some cases, the cause of this DTC may be the VVTi actuator.

In general P1349 is a misfire or ignition issue under most general OBD-II - but Toyota spec'd OBD-II has it as a VVT malfunction. Unfortunantly - hard to tell which it is. Might be the ignition timing set too advanced (VVT-i issue) or low fuel pressure (bad or clogged injector, bad or low flowing fuel pump/regulator). An emissions test could tell you which one it is. If you want to try a quick fix on your own, I'd start with the basics, change the spark plugs, air filter, and maybe the pcv valve, all these are cheap and easy. Other things could cause the problem though, so if the quick fixes don't work, I'd lean toward the injectors.

Seafoam and other additives are very good solvents that can help clean the injectors - but may not be strong enough to clean off these injectors. Injector cleaning services generally don't work that well - best way is to have these cleaned ultrasonically or replaced (very costly).

The door lock switch on the drivers side of my 2008 HHR does not light up at night. Small problem but hard to see it at night.


Don't fix the thing, cause that will cost more money!! Poor boy fix is to buy the LED keychain light that attaches to your key or keyring.  They cost around $2-$5 depending on where you go.  Probably can buy them off the internet for cheap.

I have a 2008 HHR LT that has a hard starting problem. Almost like it is starving for fuel? If you put it in neutral it starts right up? What is it doing? Thanks


IF YOUR NOT OVER 100K MILES YOUR UNDER WARRANTY.

THE FUEL PRESSURE IS PROBABLY LOW. BY TRYING TO START IT YOU ARE BUILDING UP FUEL PRESSURE AND BY THE TIME YOU SHIFT IT INTO NEUTRAL IT HAS BUILT UP ENOUGH FUEL PRESSURE TO START.
