To add cruise, you need to get a spare pulley from someone like Mad John, then install it on next to the pulley on the TB.

 

I am leaning towards the coils myself. so after 30 mins of driveing it starts to cut out..

check the following

1.coil
2. tps/isc
3. map sensor
4. cam/crank postion sensor
5. 02 sensor

when was the last time you changed the fuel filter and or fuel pump

 

Hey guys.
I changed the spark plugs and the problem seems to have gotten worse.
I changed the plugs yesterday night and today morning this is what happened during a 40 km trip.
Everything was good for 1st 20 km's of driving.

Then i started to feel the car in idle it would blip down for a sec and come up.
But still drivable so i kept driving.
The traffic got a bit bad(and car warmer) and that was when my problem happened.
The car felt like the when you have no petrol in the tank.
Eventually after a few minutes i had to pull over because the car just died.
When i tried to start it, It wouldnt even turn over.
So i let it stay for 2-3 mins off. The turned the key again and it would turn over but not start.
Left it for longer and tried starting but went off straight away even if i had it on WOT to prevent it from dying.
I left it for another 5-10 mins and started and it came alive after cranking over a few time.
I kept my foot on the gas the whole way and then the RPM went up slow and then faster at 4000 RPM.
After 4000RPM the car feels like normal.
I also found that i had to rev the car to 5000 and then let the clutch go in order to get moving cos the car has no power.
The car has no power...
The car died out once more on the way and same story..

Im really frustrated... This is my daily and i didnt even do any mods...


The following were changed a few days ago.
FUEL PUMP & FILTER
COIL PACK
PLUG WIRES
TPS
CRANK SENSOR

My brother told me it could be the coolent temperature sensor. He said when the car is cold it will make the fuel mixture rich
and lean it out when the engine is hot.

So the things that i have not changed yet that you guys suggested is:
IAC
PCV Valve
CAM SENSOR

Im waiting for advice. I am at my shop now and i have the IAC and Coolent temp sensore ready to go in but ill wait till you guys reply and change them.
Thanks

 

Tell me about your TPS. You just replaced it. what did you replace it with? What model/brand name? New?

 

wait.....

so you swapped the head, had problems in the cylinders, then put it COMPELTELY back to stock?

after putting it back to stock, the problems arised. Could something have been damaged with the previous head? damage in the cylinders maybe?

is there anything different about the car now, compared to BEFORE the head/cam swap?

If the TPS was a bad Dae-Sung, and he swapped it with another Dae-Sung, I would think the problem would change a little if it was the TPS causing the problem. I also wouldn't think the Dae-Sung would go bad so fast, I thought it took time? It's definitely important to know which TPS was used though.

 

I just remember that there was someone recently who swapped their bad TPS for a newer 2004 or so TPS and had to modify it to do so, but I don't remember if that was this guy.

 

Improbable failure: fuel pump heat soak?

 

You havn't mentioned changing the spark plugs. That should have been the step in troubleshooting, before the wires. Changing spark plugs and verifying gap if they don't work.

 

^ DTN, his first post:

 

Guys I was stuck again on the way home during traffic.
I had to pull over after 10km's of driving because the car would not move.
The engine died and then when i tried to start it would only crank but not start.
Also if i pumped the accelerator pedal whilst trying to start i heard popping sounds in the exhaust.
I think it called backfire?
I changed my IAC before i left work to a new



Redzman i swopped it for a Kefico which is the good one.




Majik there is nothing wrong with block. The mechanic did check it when he removed the faulty head.
There is nothing wrong mechanically... When the car is cold to warm it runs great.
When the car gets hot then it bogs little by little eventually switching off.
And will not start...



Well it does seem like the fuel pump but that was changed a few days ago..


I did change this DTN. Thanks for your post though.


Guys i felt like tearing my hair out today when i was in traffic and other cars were passing me..
What an embarresment. Hehe. Its the 1st time in 200 000km that my car has done this...
I think ill swap back my old IAC since its not the IAC.
Only 2 other things i think it can be.. MAP Sensor or Cam Sensor.
My car has no power when it starts bogging out.
Once the car catches momentum there is no problem.. Even while its bogging if i can catch momentum then it becomes fine.
Combustion is not happening properly at lower revs..
This is all i can think of.
Tomorrow the car is going back to mechanic. Hopefully he will sort it out.
Thanks Again for your help!!!
