TBI acting like its loading up at low speeds(idling around the woods)

[scoutillac]

When I am out wheelin or just idling through the wood lookin' for a helpless meal on four legs my burb starts kind of surging like when a carb loads up. How do I fix/prevent this problem? /forums/images/graemlins/dunno.gif

Damn I'm full of questions today.

Could be EGR, vacuum leak, fuel pressure, IAC, TPS, ....any codes?

 

[scoutillac]

No codes. Timing is set to specks and I believe I have all the vac leaks fixed. But there are so many lines. If I spray carb cleaner under the air cleaner it doesn't die out. That is how I was told to find a vac leak.

Maby check the TB base gasket. They go bad and cause vacume leaks.
BTW Spraying carb cleaner to find vacume leaks is a good way to start a fire.Bad plug wire=spark=BOOM! Water in a spray bottle works just as good and is a lot safer. RPMs drop when it sucks water in thru a vacume leak.

Thanks for the safety advice /forums/images/graemlins/waytogo.gif

Don't overlook the simple stuff as well. A distributor cap that has outlived its usefulness can cause crossfiring that will first be most noticeable at low RPM. /forums/images/graemlins/thumb.gif

It has been awhile since I changed the cap and rotor. Come to think of it I really need to get off my butt and tune it up thoroughly. /forums/images/graemlins/thinking.gif
