Is Liana Underpowered

[sameerahmed2811]

I bought Liana 2006 Rxi 1.3L. As this car has a 1300cc engine but I feel it a little bit underpowered. My car doesn't have a good pickup. It does a bit of jerking while gaining speed on light foot but no jerking when I push it on heavy foot. Engine condition is also good, there is no such issue in the engine and is properly tuned as well. Things get even worse when I turn on AC, with AC it losses more power. Liana users tell me if the car is this much underpowered or this might be an issue with my pressure/clutch plates?

There may b many things. First share your scanner readings when engine warmed

If th car is jerking, it might be a spark plug or ignition coil issue. The pickup of the car is quite good on a properly working engine.

Liana has better power than GLi how could yours is not performing well. I have personally used liana for 2 months.

[sameerahmed2811]

And what about the AC? With AC it reduces power. Is it normal?

[engnr.mubashir]

No, AC doesn’t effects the performance.

Spark plugs are fine. I've heard about weak ignition coil issues in Liana. Someone has suggested me to install Corolla ignition coil. Hope this will work

I would suggest go for original suzuki coils instead of corolla coils. Liana's are not like mehran. They hate jugaars and repairing them can be quite costly.

[sameerahmed2811]

Suzuki Liana's genuine coils are already installed. If you want me to replace them again with suzuki then which model's coil should I prefer.

[the_mira_guy_08]

Check if your engine is a M13A and not a M13AA, the ignition coils are different and are not compatible with the M13A ECU. Check if the ignition coils are weak. If they are weak then replace them.

Really? As per my information, the ignition coils for all M-series engines are the same.
