My guess is that there is something obstructing the flow of gas to the carburetor or airflow to the engine. This could be a simple fix like changing a bad fuel filter or bad air filter, or it could possibly be the timing belt.

It sounds like you may have a bad fuel pressure regulator. The fuel pressure regulator is in the throttle body housing and the throttle body in your truck works best at 13psi to 15psi, Any other setting will cause problems. Check the vacuum hose to the fuel pressure regulator at the throttle body and check the fuel pressure at the shredder valve. The way the throttle body works is for the first 75% of the throttle, the ecm uses the signal form the O2 sensors to control the air fuel ratio and tries to keep it to 14.7:1 but at full throttle it by pass the O2 sensor signal and runs the engine richer and advances the timing so you can drive with wings like red bull. The Map sensor then takes over to promote the engine to run richer so you don't run lean and detonation occurs. If there is a problem with your throttle body position sensor, map sensor. and fuel pressure regulator, then at WOT (skinny peddle down) you may be running to rich. The other thing to is if your fuel pressure drops at WOT you'll get a lean condition and then you'll have detonation ( Knocking) and the timing will be turned down to keep detonation from occurring again and that may be the cause if your check engine light too. First and easiest thing to do is change the fuel filter and add fuel injector cleaner to you gas tank, buy a throttle body cleaner and clean your throttle body to make sure you don't have varnish build up around the throttle body, just follow the instruction on the can. Throttle body cleaner not carb cleaner. Start with that and i hope we don't have to do any more to get your truck running like a rocket. Good luck and keep me posted. Be glad to help.

SOURCE: '03 Jeep Liberty starts weakly and needs gas pedal to idle

Turning over is what the starter does to the engine ...you can turn an engine over with no spark plugs in it...but you can't start it. Turning over is cranking .....the starter turns (cranks) the engine over (comes from when you had to put a crank in the front of the engine and crank it.)
Does it crank normally but has trouble starting???????

I had the same problem but I did two fixes for it (1) when I bought the truck several years ago the duel tank switch was pushed in but i never fixed it and just would switch tanks with the switch pushed into the dash. after awhile it acted like it didn't know what tank to draw from point is i finally replaced the switch and it ran, but still ran rough, (2) on the left side of the motor their is an EGR valve (it was green colored vacum hose) I replaced that vacum hose and now it runs great.

It might just need cleaning. Spray some PB Blaster around the throttle arm where the cable connects to at the base of the carb, and see if that frees up the flaps. And while spraying, fiddle with the throttle linkage.

1988 22r pickup have to pump the gas now before starting 15 to 20 times. i didnt use to have to pump the gas before every start if it sits more than 10 hours it wont start unless i start pumping the gas...


Seems like the choke is not turning on. The 22r uses a carb if I'm not mistaken. pump it a couple of times then try pressing the pedal completely down before trying to start it. Then press the pedal half way down. the point is to set the choke when you press the pedal all the way down.

There appears to be a thermal movement of choke mechanism that comes about once vehicle is warmed up. Check the chock connections, hot water pipe and linkages tight or clear.

1984 passat cl. the automatic choke runs too fast


the choke has 3 screws to adjust the unit,the choke itself will normaly be siezed inside at the age.With a warm engine, loosen the 3 screws and turn the choke untill the idle drops.

or as i did it-with a cold engine, remove the airffilter and with the 3 screws loose on the choke press the accelerator pedal just over half so the choke is engaged and the looking inside the filter housing adjust the choke flap by turning the choke housing until the flap is 3/4 closed and tighten slightly and start the car.Do remember to check your distributor timing whith a warm engine and make sure the sparkplugs and airfilter are okay as each upsets the other.

1995 Isuzu Rodeo starting problem.


Hello first thing i would start with is check your idle screw it may be set to low if the choke linkage is sticking .first take your breather off so you can see the choke linkage look to see where the plate is positioned is it fully closed have somone try starting with out touching the gas pedal if it doesnt start slightly open the choke plate if it starts you need a choke adjustment check to see if its manuel linkage, vacuum operated,or electrical. if vacuum check lines for dry cracks or splits preventing choke operation if electrical you need to test the power wire at the choke also test for good ground if mechanical check adjustment screw for curb idle to see if its set to low.goodluck please rate
