Hi guys. I really need your help based on experiences.

My car was behaving funny and took it to my mechanic.

Issues
When i start early in the morning, car fails to idle well and dies almost instantly till i apply acceleration for about 1 min and thereafter it stabilizes.

Also sometimes, car jerks at high speed say around 100kmp and when i release the pedal for 3 seconds it normalises and continues.

Ive been driving like that since it hasnt brought serious issues. My mechanic changed the Fuel pump and checked the six nozzles. He found 2 nozzles bad, which he replaced as well as the six plugs.

After the replacement, i just discovered that there's no change and now the car is becoming worse. it now has bad idling and car will only idle well when the temperature gets hotter. When at cool temp, it idles badly.

Yesterday, i did a scan and behold two codes which are P1130 and P0105

Afterwards, we searched for leaks and found one nozzle not properly tightened. We tightened it yet the car would not idle well. When ever i load the car i.e put on gear, it shakes/vibrates really bad and the rev drops to almost zero from 1000 rev speed.

Please what are the likely solutions based on previous experiences.

I have done researches on the codes, but i still need practical experiences from you guys.

Thanks in advance

 

From another forum member:

P1130 - Swirl Control Valve Control Solenoid Valve

AKA:
COLD START VALVE

The Cold Start Valve is used to provide additional fuel needed to overcome fuel condensation and additional friction present during cold engine start-up. Dependent upon, and operating in series with the thermo-time switch, this solenoid operated valve creates an atomized "swirl" mixture, which is injected directly into the intake manifold plenum. This part is also known as the "5th" Injector, Cold Start Injector, or Cold Start Device

 

Thanks for the info. Are u saying i should change the valve and all idle problems would be eliminated or try something else? Remember i have two issues. The car wouldnt idle well at cold start, and also stalls sometimes at speed up.

Thanks

 

No help?

 

Replace the part and report back.

 

Please can i get the diagramatic position/location of this two parts? i.e p1130 and P0105
