I picked up an 89 Swift a few months ago. I got it for rebuilding some yamaha rhino motors for a guy. He told me the throttle position sensor was bad but it still ran. It tended to idle about 1500 rpm but after awhile would drop down to about 900 rpm. I drove it for a while then one day the timing belt blew and I ended up smashing a bunch of the valves. I cut the wire to the throttle position sensor to make it easier to pull the head since I was going to put a new one on. Well my the throw out bearing blew up in my truck so I couldn't get my hands on a new sensor. I spliced the wires together and called it good. Then I broke the top hose off of the idle air control valve. I happen to have a 1L geo motor on the floor so I pulled that off of that motor and threw it in the swift. I got it fired up but it would idle at 2500 rpm and then would drop to about 500 rpm and pick right back up. I had no choice but to drive it to work today. Made it there no problem, but on my way home it died. It was like I turned the key off while driving down the road. It has compression, spark, and fuel. Every once in a while it fires but wont stay running.

I can't figure out what is going on. I'm going to haul it back to my house tomorrow and make sure that it is still timed right. Could it be one either the throttle position sensor or the idle air control?

Or does anyone else have any ideas.

Thank you.

check for codes

put a fuse into the diagnostics port in the fusebox, (by clutch pedal) (its the only one thats raised) and watch for the check engine light flashing

flash...flash flash = 12 means everything is good

i think a bad tps would not shut the engine while running

check the rotor in distributor for properly tightened
remove #1 spark plug check crankshaft top dead center for being @ 0 deg on the crank pulley/timming cover (quick timming keyway check)

I checked the rotor on the distributor and that all seemed good. I'm planning on checking the timing as soon as I get a chance to work on it again. I'll try the fuse thing also to see if I can find anything that way. The throw out bearing just blew up in my truck so I'm going to try to get that going first.

Also what would cause it to idle at 2500 rpm and then drop to maybe 300 and pick right back up again?

Could be an air lock in the cold start valve.. it is on the back of the intake and has 2 small coolant hoses going to it.

:goodpost:

Check the compression.

Your story is fantastic. :shock:

How did you 'blow' the throw out bearing?

Well I got the Swift back to the house, but haven't had much time to mess with it. It really wants to run when it has been sitting for awhile. It fires but wont stay running no matter what I do.

Saturday I dropped the transmission on my Dodge and had it thrown back together in about 10 hours. I forgot to order a new slave and master cylinder for the clutch though so it will sit until Tuesday night. The bearing was going bad and I knew it was but since I was still waiting for parts for the Swift I had no choice but to drive it. Then one day it just wouldn't go into gear no matter what I did. I looked into the drain in the bottom of the bellhouse and all the balls from the bearing were sitting right there. The bearing came out in pieces I'll take a couple pictures of it when I get back out there to finish it up.
