I would check the injector plugs with a Noid light, and check the resistance of the injectors. Also, check the fuel pressure regulator. What did the old plugs look like when you took them out? Did you check the fuel pressure?

I have a 2007 Suzuki xl7. When I first start down the road it seems to drive fine but within 1/2 to 1 mile it starts running very rough, leaping along. This goes for about another 1 to 3 miles. It runs...


ok and XL 7 but what engine options. gas, diesel, 2L , 2.5L?
what?
and most important , and never ever 1 time stated on this forum
what country.
leaping?

im not sure what you are saying.
it runs ok cold, and as it warms , the engine. it stalls.?
and what does same thing mean.?
my guess, it starts fine then stalls; hot.
but can you save the stall?

stalling is complex. can be many systems in the car.
but can be broken down to :
Ever did the 60k mile tune up,ever? if not why not.
never skip 60k\'s or the motor will run like garbage.


1: lost electrical power. to EFI .
2: bad engine, in that when it gets hot , it loses compression.
3: lost park. 1 or more cylinders, 4 or 6 you never said.
4: bad injection. 1 or 6 of them, flooding or starving.
5: bad fuel.
6:EGR sticking , usually this happens just before a stop sign.
7: if the stall was a bog and the fast right foot saved the stall, easy
the ISC is sticking closed.

Truck stalls when on rough roads


The truck is probably stalling on rough roads because the fuel pump float is not staying on the surface of the gasoline in the tank. Therefore, it is taking on air and interrupting the flow of fuel temporarily. It may be sticking a little and operating too slowly.
The fuel pump is inside your gas tank but can be removed and replaced by you if you are skilled enough.

Have 1988 ramcharger 5.2 throttle body it starts hard just cranks till i press on gas then when i drive up the road when i hit he gas it bogs down any ideas


Start by checking to make sure that fuel delivery to the carburetor is good. The fuel pump might not be working well, or there could even be a problem with the fuel pickup tube in the gas tank.

Engine cuts out when you excelerate runs ok then when you press gas petal it will **** and bog down


any timing or misfire problems with the plugs? If not you fuel injectors may need to be cleand and or replaced....it bogs down because too much air is being introduced in to the system. A ballance of air fuel mixture is what makes an engine run properly. Cleaning the injectors is a little time consuming but worth the gas milage in the end and the extended lif of you car without costly repairs down the road by not repairing it know.

Accelaration loss of power


I'd have a fuel pressure test done to be sure, it isn't fuel related again. Takes 5 or 10 minutes so cost should be minimal. The other thing that comes to mind is a plugged exhaust. (catalytic converter) Quite possible on a 10yr.old vehicle.
