Check sensors or clean out maf

Isuzu Cars &... | Answered on Nov 06, 2019


If problem is only on startup and when idleing, then the problem is likely IAC system, also a vacuum leak will cause the same problem.

If problem is not only on startup and idle, but also when driving, then MAP sensor and EGR system must be checked.

Check also accelerator cable state and setting.


The first thing to do is pulling out the OBDII fault codes stored in the ECM. This is done connecting a code reader to the ECM diagnostic port. The job can be done for a small fee at any local garage, and it is done for free at AutoZone.

The codes will help locating the problem.

About possible faults:

Problem is stalling when idling and during startup, but engine idling fast all the time. Problem not starting at times it is due to the fact that the wrong mixture is being sprayed, this is probably causing flooding and misfire. Since the CEL is on, one of the codes returned is probably misfire.

Check accelerator.

Check IAC system. This is composed by a valve and a solenoid that check and control amount of extra air air when the engine is idling. The IAC valve is located on top of the throttle body.

Check the vacuum system and try cranking with gas tank cap off. Vacuum system is tested using an hand tool gauge onvacuum lines while spraying card cleaner on the hoses (or heating them with a torch). If there is a leak, pressure will go up. A big leak will also do hissing noise, and will often result in a lean code when doing an OBD code scanning.

This kind of symptoms can also be caused by weak wiring to MAP/MAF sensor (MAP in this engine).

If the car also drives very rough and is revving up and down in a weird way, check the EGR valve.

As first thing I would do a code scanning. This car is OBDII. The scan can be done for free at the nearest Autozone, or for a small fee at any garage.

If you get any OBDII code from the scan, report it here, so that we can individuate the possible reason for the problem.

If you repute my solution helpful, then please take some times to accept the solution. Providing good repair tips requires time and skills, and your feedback is important for us.

Engine data plat is on valve cover. Some are forward some are at rear depending on year. The plate will give you info you need also next to plate will give you the horse power rating that is programmed into ecm.

As you have replaced the brake booster and master cylinder I strongly suggest you begin by rechecking the fitment to ensure any pedal linkage adjustment is correct and a clearance exists between the booster pushrod and the master cylinder piston.

Ensure the load sensing valve is correctly adjusted and is working correctly.

Check the brake at each wheel is in the condition the manufacturer would approve of and then bleed all four brakes using the most suitable method...

timing marks

Isuzu Pickup... | Answered on Oct 21, 2019

not starting can be from several reasons
cam/crank position sensors failing--wiring -units ---broken timing belt /chain
immobilizer not working properly--flat battery in key fob-- fuse has been removed and replaced
ignition control module failure
injector problems
low fuel pressure from pump not working
the idea is to run the fault codes to get some idea of the area to start checking and work from there

A mere 2,400km into the life of my 07 Rodeo TD 4WD, I used 4L for about 2km of medium-steep/slippery track. After stopping and selecting 2WD the 'Check 4WD' light appeared, meaning I was stuck in 2WD for the rest of that trip. Luckily I was able to complete the trip in 2WD without incident.

The dealer blamed me for 'not following the instructions in the manual' (utter codswallop), 'fixed' it, and very reluctantly gave me a scribbled set of instructions on resetting the system, which I've included below.

When I suggested that these instructions should be included in the manual, the response was 'not necessary if owners use the system correctly'. More cods.

Here's how to reset it:

1. Ignition off, hold all 3 buttons (2H, 4H & 4L) in together

2. Switch ignition on to 'reds' position (last position before start)

3. Hold in this state for 30 seconds

Hope this may be of use !!

If you don't have the vehicle handbook the dealer will be able to provide the oil specs, not that a string of numbers ever meant much to me.

I find it more convenient to go to the application catalogue of my favourite oil company and follow their recommendations, it has the benefit of being (mostly) more easily available.
