Question about 1996 Suzuki Sidekick

2 Answers

Will "bogg" down under depressed acceleration and lower RPM's. Wondering if you have any suggestions? See below for what I've done already.

Have 1996 Suzuki Sidekick. Will "bog" down under heavier load of accelerator. I've checked compression, air intake (including sensors), plugs, wires, cap and rotor all new. Timing was 2 degrees off. Fixed it. It will run fine at higher RPMs and lean out of the Bogging. Checked fuel pump, it is pre loading the motor. There also seems to be some raw fuel coming out of the tail pipe. i've almost narrowed it down to a fuel problem. Wondering if you all had any further light or wisdom to bestow..Cheers.

Raw fuel from the tail pipe I would think maybe a bad TPS, fuel pressure regulator or injector. More than likely a bad regulator or throttle position sensor. Check your fuel pressure after the regulator at idle and wide open throttle. At an idle the pressure should be 20-30 psi lower than at wide open throttle. If your getting to much fuel pressure it can cause it to bog down and lose power due to extremely rich conditions.Will also have strong exhaust fumes.

    not TPS can ever do that. sorry. nice repeat though, that is correct misfiring does drop engine power, after all each misfire, is lost combustion times the hit rate. but is called misfire, and yes, gas dripping from any tail pipe would cause, strong fumes, and is the KEY EVIDENCE here.

    oh ok, a bad tps showing wide open throttle causing the injectors to dump excessive amount of fuel could never be the problem. Lol have you ever worked on a fuel injected engine? Or is being a troll with your broken English your strong point? a simple test with a multimeter can rule out tps sensor in about 30 seconds but yes it can cause severe hesitation at low rpms if it's telling the ecu you have the throttle wide open and it's only open a fraction because it will dump way to much fuel causing a super rich condition. engines don't like to be run super rich or lean. need that sweet spot of 14:1 air/fuel ratio. and as far as a repeat my post was before yours. oh yeah misfire can be caused by it running to rich and soaking the plugs. go troll somewhere else with English.

    go back to EFI school, the MAF sets fueling, the TPS, only causes, enrich mode, on a fast right foot. and on acceleration, the 02 is not used,(called open loop mode) and Too Rich , is correct english bottom wipe.

    go back to your ASE instructor, his car is not "Alpha-N type " like used on race cars.

    Checked TPS (fine). Compression was fine at 150, 150, 155, 150.
    Checked fuel pressure regulator (fine).
    Tested spark wires, plugs spaced fine, cap and rotor are new. Timing is spot on. System is not overpowered by electricity.
    Next is to check egr valve...
    Any other ideas? I appreciate the help guys.
    And Mr. Carrol. I meant to put a "helpful" review for your comments.
    I am hoping I'm close to a solution.

    My girl and I bought this car together and are hoping to go on grand adventures in it!

Compression at 170psi or more (Wide open throttle?) if not
but way low, the timing belt is slipped. (a 60k service point)
sure my list is endless. not knowing data. like real compression numbers......
first off the cluster has warning lamps is the CEL on , keyon>?
and after starting does the CEL go out> if not scan it.
all 96s (uSA) any scan tool sold works, for this car.
even 9 buck tools. hint?

seems it has a leaking injector, no? that much fuel
and is not bogging ,its lean not lean , its rich misfire. loss of power
and id bet for sure storing P0300s or close , yes>?
why not use a scan too.
and check all 4 spark plug tips of fuel soaking.

if one injector does leak, the next test is the NOID lamp
to see if the ECU is bad , causing the injector to stick on.
NOID lamp sticks on. means that.

see misfire page. (its not bogging, its misfiring i bet.)
this is the first things to do with EFI find out if to rich or too lean, x4
G16B engine.

spark timing is done with the timing freeze jumper planted
or you did it wrong.

other causes of DRIP DRIP of fuel>
fuel pressure not 30 psi but 60,
a: return line blocked.
b: ;Fuel pump reg at fuel rail bad.

injector leaks.
ECU injector drivers shorted (noid test)
spark plug wells full of oil ,do to no 60k service and new gasket there.
same full of water, doing pressure washing jive.
Cam belt slipped, (oldest story on earth, lucky its not interference engine like stinkn hondas

here are all ways to misfire (50 ways)
but not as many tests. to find it. just simple tests.
(is it rich or lean, is it one cylinder or all) etc.

Testimonial: "Ok. Thanks for the debate of the issue guys. My friend has similar motor and will lend me his tps (which works fine) to test it. Compression tests showed 150, 150, 155, 150. Those were spot on. The wires cap and rotor showed a good amount of electricity flowing through... I forget off the top of my head what it was but electricity is fine. I'm leaning towards a overly rich fuel moisture from either the injectors or tps. Will keep you posted on the results."

SOURCE: no power when accelerating

Once you rule out some kind of ignition problems,; spark plugs and wires, ignition timing, distrib. cap & rotor, the cause may be low fuel pressure from a failing pump or clogged filter. Listen to the pump in the gas tank. If its been getting louder lately, have the pressure tested.

SOURCE: White Smoke From Tail Pipe/Exhaust

It often means that you are burning antifreeze. You asked if it needs antifreeze, have you noticed any leaking out of the reservoir tank while you are running it? Sometimes when the head gasket goes it will produce a passage for the antifreeze to pass from the capillaries into the combustion chamber. It is easy to check if you have an air compressor. Remove one of the rear sparkplugs and the radiator cap. Fill the radiator and then push some air into the sparkplug hole (get a good seal in case a valve is open). Repeat with all the cylinders and watch for air bubbles coming up into the radiator. If bubbles come up or fluid is pumped out, the head gasket is blown and must be replaced. It is more likely to happen at the back of the engine because it is farthest away from the fan and therefore gets less cooling. Also check your oil for discoloration. If it is a brownish color it could mean your oil and antifreeze are mixing and has the potential to damage your bearings

SOURCE: finding truoble codes for 1994 suzuki sidekick

if you live in the states... just go to an autozone... they will scan the codes for free. you may also be able to retrieve the codes by turning the key off and on 3 times and counting the amount of times the check engine light flashes. almost like morse code... when you reach code 55 that's the end of the codes. this does not always work.

Car boggs down when i accelerate

Sometimes this is a crankshaft position sensor problem. The sensor helps regulate fuel pressure by monitoring RPM. If this sensor under reads your RPM, then you will not get enough fuel for the RPM.

I have a 1996 Saturn Sl2. It ran out of gas one day and sat on the side of the road for a few days. Well, I finally got it towed home, and changed the fuel filter. The fuel pump is good. But, it is smoking...

Try changing your engine temp sensor, it won't triger a fault code but sets ecu to a defalt setting of -20 or 200 degrees, causing an over fuel situation. Not a garanteed fix but for under $20 it is worth a shot.

The engine boggs down at high rpm. For instance, hesitates and boggs down when going up a hill or highway speeds. Idles normally and runs fine at low speeds.

if the fuel filter hasn't been changed do so, if the fuel filter is ok and has been changed out due to this problem you will need to monitor the fuel pressure under a load and make sure it doesn't drop below 45 PSI, it it does you will need to replace the fuel pump and the fuel filter. U also do say if you have a check engine light or have had the system tested for trouble codes that may be triggered by this loss of power problem.

93 chevrolet truck bogging down on acceleration

Check intake gaskets. Pour warm soapy water on the gasket when it's running. If it bubbles like crazy, you have a leak. 2. Check timing. Shoot a timing light at the crank mark. If it jumps around a lot, your chain has jumped. #3. check cam. Remove valve covers, run the engine, and see if they are all raisng the valves the same. Put a piece of cardboard along the bottom, and fold it around a little, so it forms kind of a " half valve cover". That way you won't lose oil everywhere, and make a mess, or a fire.
