    thanks for the info... i didn't mention that it is a straight drive and i live where there are no insp. i guess that means that there isn't a carb that would go on this intake. the reason i want to change is the harness to the ecm is damaged and it would take some doing to change over, not to mention hard to find a good used one.well thanks again.

You can but your going to put lot's of money and time in to it. The electronic's to the throttle body is tied in with the ecm which also controls the transmission shift points and firmness to the throttle body blade position. If you change it of to the Carb your going to have to replace the intake manifold and and distributor and buy a painless wire harness to tie in with the transmission shift points and you may even have problems having the truck pass emissions if there are any missing for the year and make of vehicle. Unless your going to have it off road use only like a race car. Used to be a time where it was free for all then it changed that you can not even swap a older engine in a car older then it's mauvatured date which mean you can put a 2009 corvette engine in your truck but can not put a 1979 corvette engine in it if your truck is 1980.

    You can get a wire harness from Auto Zone or from painless wire. Even EBay, keep in mind mist wire harness don't change from year to year. What ever year and make your truck or car is you can do a cross reference to the newest wire harness that will work on your vehicle. Good luck and keep me posted. Here is a link that you may be interested in, since your playing with the 4.3

How do i find my fuel sensor on my 94 safari van tbi motro

You don't have a carb

No fuel sensor on a TBI

There is no trying parts on any vehicle

You component test sensors & other items to see if they work
correctly & find the real issues

Parts are only installed when they fail a test

There are no brains either & computer modules seldom fail

Where to locate and clean throttle body

TBI is the part where the plastic duct coming from the air filter housing mates the engine. The part where the clamp attaches on the engine side is the TBI. The TBI has attached the Throttle Position Sensor TPS and the Air Intake Control Valve AIC,
A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

New rebilt carter yfa installed, but idle at 3k all adjustment screws backed out, ? the 2.5 L 4 cylinder came from P O with a jury rigged rochester carb of 77 ford vintage, hard to start so I got the...

The 2.5 L engine is the Pontiac Iron Duke sourced from GM since it was still AMC. They came with Rochester carbs, while Ford used Holley 2 brls on their 4 cyl engines and Chrysler used Carter carbs. You might have the wrong carb and the throttle plates are sticking on the intake manifold. You can try using a carb adapter/spacer. If you drive off road I would suggest buying a TBI throttle body injection system from a junkyard, and pick up a electirc fuel pump. Either new from a speed shop or used from a newer Jeep with a 2.5 L TBI engine, you'll need the computer, harness, relay, sending unit and lines as well. But you can pick up everything at a pick your part yard for cheap (some yards have all you can carry in your hands for $50 days).

I'm wondering about 1993 Saturn station wagons. One website describes two models, the sw1 and the sw2. Another distinguishes two fuel injection types for that year's wagons, mfi and tbi. Do they...

mfi = multi port injection
tbi = throttle body injection
the way to tell is look on the intake plenum and see if there is a "carb" sitting there. That's tbi.
Intake plenum with 4 or more fuel lines going to each cylinder is a "MPI" (multiport) system....accordianman
