why my car jerks and stalling?

Salam Spectrans,

Most of all i would like to emphasize that why ur car jerks and worst still STALLING.?
There are few main reasons that occurs on yr Spectra Faulty parts.
Do check ur

1. Current flow from ur ignition coil via plug cable and spark plug.

Ignition coil if faulty will lead to inconsistence of current flow to ur cables.

I would fully recomended used high performance plug cables where its has a high capacity on extreme heat where its 10.2mm thick silicone cables where driven by 3 core for each cable.

Fully compatible with high performance plugs ie Denso IRIDIUM power which can last up to 50k km.Its a superb plugs to install to our spectra.


2. Another reason why our car jerks or stalling?

As most spectrans is unaware of how important is yr Positive Crankcase Ventilation (PCV valves) function and effect on yr engine system.

The pcv valves marked is where its located.
This systems helps to reduced emission from yr engine.
Its a small spring attached inside ,loaded with spring valve.
The valve will controls increase or decrease the air flow as to regulates it in our engine.
Another hose attached to throttle body for good mixture of air and fuel.

The photos indicates that crack PCV valves and the new ori valves. Need to replaced at once.

Must replaced ori genuine parts.

New sets of PCV valves assy, full kit with pcv hose via throttle body and engine manifold.

Faulty and bad pcv hose that need replacements.

Ori genuine pcv hose must be replaced every 100k km as to have a proper engine response.

3. The other reasons why it jerks or stalling.
check ur fuel pump assy is working?
check ur engine compression and if its more than 10 years its better to do top overhauled

So spectrans anyone of u come over this situation and need the ori genuine parts kindly contact me @ 013-7849798.
