metro engine install and surge fix

bought a 93 geo metro the other day that had a pretty noisy knock and smoked like crazy. i drove it home and prayed on the way home i wouldn't pass a cop because the thing was smoking like mad, used almost a quart of oil in 7 miles. anyway...bought one of those JDM engines ($300 with 1 year warrenty) pulled old engine out, swapped the intake and exhaust manifold over and dropped the new engine in, took about 5 hours to swap everything over and get it running (i love my new car hoist :-) )
found easiest way is to pull the engine and tranny as a unit and split it on the floor. after i got it in and new engine fired up at part throttle it would rev up and down about 500 rpm all by itself, wouldn't do it at idle or past 1/2 throttle. also check engine light wasn't on. unplugged the TPS ( that kicked the check engine light on) and tried throttle again, was doggy but no more surge so i grabbed a spare TPS i had on another throttle body swapped it over and it runs perfect now. sure glad i have a ton of spare parts, they wanted over $90 for a new one.

Way to go 'vette! Quick question, did you do your entire engine swapout in 5 hours? If it did you're a lot faster than I am. It usually takes me an entire weekend (including a new clutch kit).

pull old one out (1 1/2 hour)

transfer intake, exhaust and clutch to new one (45 minutes)

install back in car (3 hours)

times are rough guess, took just over 5 hours total

I need a car hoist :( I did mine with a craftsman wrench set, all by my lonesome, lol. But, I had to change everything under the hood, so it took me about a week(2 hrs/day for a week) That engine technically is light for an engine, but when you're lifting it into the engine compartment all by yourself, DAMN, is it heavy :icon16:

i do enough engine swaps that i have a engine hoist

Autozone wants $125 fo ra TPS. Does anyone have a spare they would like to get rid of cheaply? Apparrently I need you.

what year metro do you have, i might have a spare

I have a '92 & '93, both convertibles, but the problem is with the '92. Sure hope you can help.

will take a look in my spare parts bin and see what i have and make sure it matches the one on my 92 convertible. will post tonight what i find

Thanks, I appriciate it.

i have 2 of the same style left, whats the part number on yours, should be 18590-?????
what are last 4 or 5 letters and numbers?

I'll look when I get home tonight. Thanks Crvett69

find those numbers yet?

Sorry for the delay Crvette69, got called out of town unexpectidly. I will get the numbers this evening.

Crvett69 P/N is 198500-0450. Sorry again for delay. Just a bad week.

ones i have are different numbers, sorry. will keep eyes open for correct one though

Swapped the TPS on the 92 w/ the TPS from the 93. Same P/N. Had the same results. Could it possible be the EGR? I did get an error code of 23, but don't know how this would effect the loss of power roblem.

code 23 is intake air temp sensor bad. its the one that screws into the side of the air cleaner
