i recently did a swap into my geo metro, 94 engine into a 90.
for some reason the engine is running very weak.
tops out at 65mph
sputters while accellerating through all the gears
i put the intake and exhaust from my old engine on it and thoguht it should run fine, but that is incorrect.
What shall i do!?!?!?

Did you swap the MAP sensor as well??

yes i did.
that blew out like two weeks before the swap.
but it is not from the same gar the engine came out of.
could that be a problem?

does it need to be the map sensor from the actual car, and intake?
or the engine? :?:

no, just the same part number as the original.

You don't mention where the motor came from, is it new, used? First thing I would do is check compression...

ahh no i didn't
it was a spare i had in the yard.
had the head rebuilt.
but last time i checked the motor it said 55, but i think the pressure guage is bad, i just put a little nipple into the hole in the intake that is supposed to have a small air filter check valve that leads to the vaccuum advace. so that helped a little bit.
but i still dont know.
when i put exhaust on it, i dont think the converter wasnt full, but that could be. dont know

help me out

Would love to help you out if I had any idea at all what you're talking about.

If your original engine had a vacuum advance distributor, then you need the vacuum advance distributor on the new engine. Your computer doesn't know how to electronic advance, you're running with no advance.

Find out what the compression is, 155 is worn out, 55 probably wouldn't run at all. Engine warm, all plugs out, throttle wide open.

i have the same intake, axhaust, water pump, distributer, thermo and everything from the old engine.


and i was saying i thought the cat converter sometimes get full on the exhaust and dont give the engine the correct backpressure, so that could be it.

and when you said all that you meant warm up the car, take the plugs out of all cylinders, then check the compressions of each?

You mentioned plugging a vacuum line that is supposed to go to the vacuum advance. Everything needs to be hooked up as the factory intended first, then you can start troubleshooting what the problem is.

When doing a compression test, warm the engine up, remove all 3(4) plugs, open the throttle completely, then check one cylinder at a time. A good result is above 180, 150 to 180 is tired, anything below 150 is a problem.

If you think it is a bad cat. Loosen the exhaust pipe from the exhaust manifold and run the car up to 60 again. I will sound loud but will tell you if your exhaust is clogged up.

I'm amazed at the compression numbers being offered up. Are those factory numbers (>155)? I bought an XFI for $100 that would just barely run if pull started. Checked the compression and found 120, 100, 70. Had 3 burned exhaust valves, but the engine still ran, pretty crazy.

well turns out the timing cant be set at 5 OTDC on this engine.
turned it to 20 OTDC and got 200 miles to ten dollars,
the next 10 dollars went back down to 150 miles though.
i dont get it.
the last ten was 170.
im sure this is cause my driving.
but not 100% on that.

Never heard of checking compression with the engine running. 155 minimum is the factory recommendation for a dealer to send a customer out the door. It will run below that, but not well. You're going to get crappy mileage and performance and possibly do more damage driving it like that. Usually when they're below 120, they'll run but have trouble starting. Once it's running things are happening so fast that compression can't leak out as much, that's why compression is checked on the starter.

I assume by OTDC you mean BTDC. Sounds as if you didn't short the jumper before checking it. With the jumper shorted 5 BTDC will be near the center of the adjustment slot, the car will run better at 10 BTDC, with the distributor turned toward the drivers seat, near the end of the adjustment slot. Some engines will run without pinging all the way at the end of the slot but that's usually a sign that you've got a compression problem.

running compression test. it will usually pinpoint weak valve springs. at the usual cranking RPM a weak spring is strong enough to hold the valve closed. with the engine running at idle rpm or slightly higher a weak spring will allow the valve to bounce off the seat causing low compression
