Just wondering which Toyota wire I should use to power the external coil for my TBI? I took a picture of the three wires, and there's one of the coil itself. The gray connector is the 12V coil power supply, the large pink wire goes to ignition "on" power for the distributor, the white wire is hooked to the tachometer. The black connector has the smaller pink and white wires which goes to the...

My 95 chevy has the TBI big block in it, and it has a miss to it. Runs great down the road, and doesn't miss at all, however when giving it very light throttle it misses pretty good. At idle in park it has an intermittent miss. At idle in drive, its very smooth with no miss. Accelerating it has no miss. On deceleration, there is a miss. When in park I can give it some ...

Whats up folks! Listen I want to rebuild my TBI as stated in tittle. Having trouble locating one, and they seem to be different from Motor to motor, and years. I thought, as it looked like they were all the same but guess not. You guys have a source with a good price for a complete TBI gasket/O-ring kit for my........ 93' S-10 4.3L

Have a 1990 with 3.1 TBI engine. Fuel pump + filter replaced about a year ago. Well maintained (plugs, wires, dist. cap+rotor replaced/in good shape). Fuel pump relay energizes when key on and when engine runs. I hear the fuel pump whirring in tank while relay is energized. It always starts, but only runs for a few seconds each time (about 2-5 seconds). I removed the plastic cover on Fuel ...

Okay, so I'm pulling off the intake manifold and valve covers to change gaskets and hopefully fix a couple of problems. I also have sitting here in the garage my new (to me) 4.3 TBI that I want to install. I figured since I'll have the intake manifold off, I'll run it down to a machine shop and have them bore out bigger holes. My question is this: I want to test my engine with the ...

I just picked up a 1995 s10 4.3l tbi 5 speed. The rpo code for the engine is LB4 and vin number is z. I have an edelbrock 4.3l tbi intake manifold 3713 that I would like to put on the truck but summit says the manifold is for up to a 94 truck and the valve covers on the truck say vortec. I looked at the intake manifold on the truck and the mounting bolt holes look like there in the right spots...

Can someone give any advice regarding TBI Financial Services please. To cut a long story short, around ten years ago I had a loan with HFC Bank for £5000. I had to give up work due to injury a few months after taking out the loan and agreed with HFC to make a reduced payment of £20 a month. After another few months I got a call from HFC asking me if I wanted to pay off the loan for £1500. It ...

Kind of stumped with my truck (1988 GMC K1500, bone stock 350tbi/700r4) Went to start it a few days ago, started fine like normal but idle was kind of eratic. I let it warm up to temp and it made no difference. Long story short, it will not rev up, hold constant RPM, idle, or show a check engine light. I tried unplugging the map sensor and it idled fine, still missed a little and ...

ARE these interchangeable? I am looking to put my 1991 2.8 into a 1987 S10 (currently same motor but blown). If I do a completely motor swap, including the flywheel from MY 1991 motor will everything work - I plan to make my alternator and AC system as well). I am hoping this pull (and pull) and install, bleed the brakes and start er' up and drive it home?? If these two run on ...

My Truck is a 91 Blazer TBI 4.3 4x4 W/ a 700r4 tranny. Im looking into buying a 350 to start my swap. I want to do this as cheap as possible. Now im going to keep it simple and use my tbi on my truck. Do I have to buy bigger injectors or can I use the ones I have off the 4.3? What are the cheapest swap headers and motor mounts? Can I use the 4.3 oil pan or do I have to buy another? If ...

Hello this is my first time posting. I know somewhat of cars but dont have the time to work on them. I have a 94 S10 4.3 5 speed TBI with about 211000 miles on it. Now for my question while driving it between 3rd to 5th it will sometimes bogg down like its losing power and sputter and such. Any Ideas on what it might be?

What parts do I get for my car? Sort of a sequel to my previous thread. I have a 94 base stealth, and when I google the vin I get it listed as a " 3.0L V6 TBI 8V " but when I go to rock auto, there are just a bunch of MFI's, no TBI's. So I just went ahead and went with the first option, which seemed to have the majority of parts. ...

I pulled this weber carb off of my 89 yj 4.2L, it ran great but I've installed the howell tbi, so carb goes to ebay. BUT, I can't figure out what it is, I THINK it might be a 38 DGES but I'm not sure.. It has a few markings: on the front: a number 1 with a circle around it and Made in Spain on the passenger side: ???A3 (not sure what the ? letters are) M3442 On the rear: ...
