Car stalls continously driving me crazy

Appie07

hi, I have an astra from 01. Its running on both lpg and petrol. For while I have this problem that the engine stalls when I stop at the lights. sometimes it stalls when I press the gas pedal hard from idle, driving or not its the same. I looked around and could not find anything about it. this stalling really drives me crazy

anyone who had a similiar issue?

Have you had any lights on the dash?

Have you got an egr valve or has it been blanked?

remove and clean the throttle body and blank off the egr valve (y)

The EML is off, I cleaned the throttle body last month also blanked the egr off together with a cheater as adviced on this forum. I am glad I did, runs better now. but still has this stalling problem. It goes to low revs where it shakes the car and jumps back whenever I stop at some traffic light.

Have you changed the spark plugs?

Airfilter etc?
Could be chains stretched so its out of timng maybe?

It may be worth changing the CTS (coolant temperature sensor) which also controls the fuelling.

I changed the air filter and spark plugs to platinum last week. Both of the chains has been done in november since it was rattling :eek:

I will do that one Kevin. Does the CTS of VX220 also fit the Z22SE, I looked at your guide and they look the same.

Does it stall on lpg or petrol? Have you serviced the lpg side of it recently?

Appie07

I recently converted it to LPG. It happend in june. At the LPG garage they told me that the lpg side of the car is good. The car runs worse on lpg than benzin. The revs doesn't drop low that it shakes on benzin but it does stall randomly on it sometimes. This is very rare on benzin tough.

I'm sure they are the same. The Opel part # is: 13 38 441 (GM: 15326388)
The resource guide for changing the sensor was created by @[deleted]. 🙂

all z22se coolant sensors should be the same (y)

Appie07

I will get the coolant sensor and let you know about the progress. I think its about time that I introduce myself, since I followed alot of advices on the forums. I didn't do that till now cause I am a complete amateur and I'll mostly taking advices than giving them
