First when you say it bogs, does the motor stutter or does it just go flat? A very good test to determine if the problem is to much fuel or a lean situation is while riding get in top gear with a load on the motor at full throttle. Slowly roll out of the throttle about 1/8th throttle and see if the motor picks up RPM's. I'm suspicious that you may possibly have a plugged air filter or perhaps something blocking the air inlet. Does the bike get worse fuel mileage? Have you checked the valve clearance lately? Tight valves are notorious for the problem you are having. Please contact me with test results and I can further diagnose your problem. I'm confident we can resolve your problem as soon as we determine which direction we need to go.

Engine bogging at all speeds


Hi, Timothy start with # 10 and 11 if it is a California model check the evap/emissions canister for integrity and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Spark plugs in bad condition or partially fouled.
4. Spark plug cables in bad condition and leaking.
5. Spark plug gap too close or too wide.
6. Faulty ignition coil, module, and or sensor.
7. Loose, dirty, or corroded ignition module connector at crankcase.
8. Faulty CKP or CMP, MAP, ETS, ATS, TPS, O2 sensor.
9. Intake air leak.
10. Water, dirt, or rust in the fuel system, carburetor and/or filter.
11. Fuel tank vent system plugged or carburetor vent line closed off.
12. Vacuum line from intake manifold to fuel valve is broken, cracked, pinched, or missing.
13. Carburetor controls misadjusted.
14. Damaged carburetor.
15. Incorrect valve timing.
16. Weak or broken valve springs.
17. Damaged intake or exhaust valve.

I have a 97 jep cherokee country 4.0 and can't find the fuel filter...my jeep acts like it's not getting.gas and wants to put? when im going 60 or so and i changed the fuel pump but its still doing it


if you follow the fuel rail gas line, it goes to the filter.
for sure.
4.0L 97 , we have the FSM to see all that , ive posted it 100s of times here. that link.
please explain the bog more clearly.
cold or hot engine or both.?
is it just tip-in throttle bogging , only then POWER catches, up?
while bogging can you go to WOT and see if it has full power now?
ever get a full 60k mile tune up with new spark parts. and filters.
is engine misfiring.
is engine idle too low rpm or too high with a hot engine?
is fuel old.
did car sit for long time ? unused?

"not getting gas" can be 2 things, bogging or misfiring
they are night and day different, one is like pulling a dead weight
the misfire is violent engine shaking,
see?
and 2 different diagnostic paths due to that ...

if wot is ok, then that implies fuel pressure is good. and filter.
see?

WOT = WIDE OPEN THROTTLE.
i drove a 99 XJ for 300k miles. and know it well..

free fsm
click fuel system here 96-2001 xj

see that page? page 14 in PDF
if you changed the pump, you had it in your hand.
unknowing
its on top of the fuel tank pump RACK.

if engine is tuned up,?
and power is low at wot,
i check fuel pressure live.(under varying engine loads)
if the pressure is out of spec, i get a new filter and PPR.
if pressures are in spec. dynamically.
i find out why the PCM is under-injecting.
ask how. its not hard.
(bad MAP?, , injector balance tests?)

My jetta will start but when you give it gas it dies. ive replace the fuel filter maf sensor and as a result with messing with the throttle body, im replaceing it as well, i hooked it up to a computer and...


Its a computer controlled motor so yes if one thing gives it a bad reading the cpu will try to counter the issue and give to much gas or not the right amount of air to the intake... Just from what i have happen to me I would look for a leaking vaccume line or a clogged cataltic converter befor replaceing the sensors both can give a false o2 reading on the computer and seem to be more common on most cars..

Bogs down on acceleration


buy 2 fuel filters. buy can of SEAFOAM at parts store. use 1 f filter to replace old one(you'll probably see old looking gas, with an odor).Pour SEAFOAM into tank. fill up with PREMIUM gas. after about 100 miles change out fuel filter 1 last time..add SEAFOAM every 3-5000 miles and you should be fine. the ethanol in the gas turns to goop and adds water to your fuel, and puts carbon on your valves and through out your emission and fuel system. The ethanol will be alright as long as you follow these instructions. and the SEAFOAM will keep you from having line freeze up in the cold months ahead, and will give you better gas mileage. good luck.

At Idle Runs Fine, 50% throttle runs like ****


It could be a lot of things, if you can run some component testing. You should be able to narrow it down. Test the TP, EGR, IAC sensor, Look, does the car act up at high throttle while in neutral or just when its in gear? You may want to check the timing and look inside the distributor for any signs of water, rust, or carbon build-up.
