Hi, I've just been given a 96 swift by a family memeber. It's misfiring, but only occasionally. Sometimes it'll misfire but sometimes it won't. The rev counter jumps alot when it does and it only ever really happens when the car is running at low revs or when its wet. Can you help?? I've looked it most of the places I can think of with my knowledge, but still can't get rid of it.
Thanks guys, Well, I've tried most of the ignition, I haven't changed the HT leads in a while, so might give them a go. Then go for fueling. I give you credit for the speedy response aswell.
Thanks

Sounds like you you need new spark plug wires and also I would change the cap and rotor. Since it happens when it is wet I am really thinking that there is a break in the wires, that will definately cause that.
Could also be the fuel filter but I would do the tune-up > (Wires, Distributor Cap, Rotor, Spark Plugs) first if you have not done that already. It is well worth the money and should be done as regular maintenance anyways. It will also increase your power. Hope this helps!Could also be the fuel filter but I would do the tune-up > (Wires, Distributor Cap, Rotor, Spark Plugs) first if you have not done that already.

hot engine or cold engine or both , 180f is HOT. no year stated. "The Suzuki Swift began in 1985' and ended in 2001 here.(usa= hear,and is usa forum) but not else where. and had many engine choices world wide. sold world wide, so where is yours. be the first ever to say country and engine size in one post... shock us with that? please.
stalls you mean stalls right,? not misfires and stalls or misfires and rpm drops below 800 hot. misfire can happen under all engine loads or speeds and even idle, so are you saying it only acts odd at hot idle?
misfire has over 50 cause I an find it in 1 to 10 tests, using tools. got tools or just want a wild guess.?
wild1: ever get a full 60k mile tune up this decade. per the operators guide list covering SAME. most drivers ,drive till it stalls. is that you?
the title is contradiction " check light on, no codes."<< totally wrong scan it one more time with a REAL scan tool this time. (there are DTC errors , or codes as you said)
what does bad idle mean? misfiring, or idle speed too low or too high? RPM, or surging?
say what that means please. and more important is engine hot or cold ? failing.???? or both???? there are over 50 causes. but can be broken down to simple physics and gauges. 1: engine bad, lost compression. 2: engine cant breath, dirty air cleaner 3: ISC stuck closed or open or just stuck. (bad idle air supply) 4: bad spark, 1 or all 4 (never had a tune in this decade. 5: cam drive, slipped (belt) causing #1 failure. 6: air fuel mix too lean, and causes rpm drop and ISC fails. 7: air fuel mix too rich and misfires. 8: egr stuck open, it misfires and ISC gives up. 9: cat clogged, engine cant breath #2 like. 10: and the vast other reasons for misfire.
we cant drive it, see it or hear it misfire, so.....????
there is a test for all 10, ask. or get car serviced.
which engine, what year.?
egr struck open , partially is #1 cause of low idle
and never getting a tuneup.
the ECU, does all it can to hold 800, hot, all day,no matter what.
but
will fail if:
1: not tuned up, called misfire. (shudders is misfire)
2: too lean (low fuel pressure.)
3: leaking injectors, more misfire. (or clogged)
4: egr stuck open a tad, or stalls if open fully.
5: ISC stuck closed.

P2096 Suzuki - Post Catalyst Fuel Trim System Too Lean
to see this steps read the FSM. it covers this.
lots of tests. not guessing.
Low fuel pressure
- Misfire condition
- Large vacuum leak
- Air leak near sensor
- Plugged catalytic converter
- Lean air/fuel ratio
- Faulty front O2 sensor
Misfire could be a number of things: a) spark plugs - change them if used over 15K miles - inspect/regap. b) spark plug wires - change them if over 15K miles - inspect c) ECM (electronic control module) - test with HEI (high energy ignition) tester.
The vibrating tells me that the engine is running on less than its normal
compliment of cylinders - the shaking is produced by the imbalance
caused in the engine by one (or more) cylinder(s) not firing at all.
The "Check Engine" light probably is coming on due the the misfire condition. Go to Pep Boys or Advance Auto Pats, where they'll tell you (free) your codes causing the "Check Engine' light to be lit - the code coming from your truck's computer will probably be one or more of: P0300 - Random/Multiple Cylinder misfire detected P0301 - Cylinder 1 misfire detected P0302 - Cylinder 2 misfire detected P0303 - Cylinder 3 misfire detected P0304 - Cylinder 4 misfire detected P0305 - Cylinder 5 misfire detected P0306 - Cylinder 6 misfire detected P0307 - Cylinder 7 misfire detected P0308 - Cylinder 8 misfire detected P0313 - Misfire detected with low fuel

I wouldn't worry about the 02 code it will clear when you replace the coils. to be positive that the coils are bad, swap them with another cylinder and see if that cylinder misfires. 90% of the time it's the coil. Let me know
