LPG Discussion Forum

Hi guys i want to replace my coil pack on my astra mk 4 after trying other things car still running @!## and mileage is down per tank refill so what my question is does anyone have the part number also does the coil pack from an astra mk 4 petrol car fit or is it a pacific part for the lpg astra ?

Unlikely to be a different part but unless you have a noticeable misfire the coil pack is unlikely to be the cause of your problem.
Start by examining the air filter and checking the plugs and plug gaps
Vauxhalls are very prone to problems with the EGR valve gunging up which causes rough running, increased consumption and general loss of performance.

Thanks for advice going to clean out EGR valve out this weekend now i know where it is on the engine.

I had the EGR mapped out of the ECU on a Z16XE (petrol/LPG) engine after it failed twice in a year.

After it has been mapped out, remove EGR and with an aluminium drinks can (steel ones rust) make a template to blank off the port the EGR sat in.

You will need to locate a VX dealer who will re- programme your ECU to ignore the EGR valve. Some will happily keep replacing the valve at £150 and others will do the proper fix. Corby VX charged me £42 to re-programme and fit blanking plate. Kettering VX (same company) , happily replace at £150 a time.
Your problem could be anything though, the VX forum is very good as is this one for VX LPG problems.
