99 Suzuki Swift 1.3l cutting out
Permalink  
 

A 1999 Swift 1.3 cutting out has a few well-known culprits. Roughly in order of likelihood and cheapness to check:

Idle-related (cuts out when slowing, stopping, or idling)

Dirty throttle body / idle speed control (ISC) valve. Very common on these. Clean the throttle body and ISC passage with throttle body cleaner. This alone fixes a lot of stalling.
Vacuum leaks. Perished hoses, a cracked intake boot, or a leaking brake servo hose make idle unstable. Listen for hissing with the engine running.
Throttle position sensor (TPS) wearing out, which gives erratic idle and hesitation.

Cuts out randomly, even while driving, and restarts after a pause

Distributor / crank angle sensor. On the G13 engine the sensors sit in the distributor, and heat-related failure causes sudden cutouts that restart once it cools.
Ignition coil or igniter module failing when hot.
Main relay or fuel pump relay. Worth swapping with a known good one. If you hear the fuel pump prime when you turn the key but not after a cutout, that points to this area.
Fuel pump or clogged fuel filter, especially if it loses power under load or on hills.

Hi folks,

I'm brand new and posted this in the introduction too.  Sorry about the repost, but I thought I might get more responses here....

I just bought an APEX two seat untralight with a 99 Suzuki Swift 1.3l FI engine, rated at 95 hp. The motor was taken out of the car, completely gone through by a reputable machine shop and had an SDS ecm installed to replace the factory ecm. The motor only has 44 hours since the rebuild and it has two fuel pumps, one in the tank and an external (in line) pump. When tied to the floor, the static engine will run flawlessly at any speed for any amount of time without any issues, but when we are taking off, just as we are at the end of our take off roll or have left the ground, it the engine loses power (the worst possible time) but does not stall. It will again run flawlessly once we have stopped accellerating and we can not replicate the problem in any other configuration. I have taxied it for over an hour at varying speeds and it never misses a beat. But it has cut out three time on take off (it is a much longer accelleration than just taxiing) and I am about to go crazy. I am not sure why acceleration would matter, but it seems too. Any suggestions would be greatly appreciated. Let me know if you need any additional information. I am currently in Flagstaff AZ and the trike is in Casa Grande where I am taking lessons -Bruce
