Corsa-B.uk - Vauxhall, Opel and Holden Corsa B Owners Club

basically my corsa is a 1.4 8v spi breeze, its a 1998 and recently it's been running like poo, one day it seemed to be running absolutely fine when i parked it, the following morning wheni went to use it it struggled to start for a few seconds and then rumbled into life, since then i have been getting the eml light coming on intermittantly, so i tried two error code reading things i read about online, the paperclip test, and the one where you hole in both buttons on the clock, the confusing bit is that according to this website: http://www.topbuzz.co.uk/info/fault_cod ... _codes.htm my car should be using 2 digit codes on the paperclip test right? and that set doesn't have any zero's, but the flash sequence i get goes 10,2,10,10 which i read as 0200, but this code doesn't exist? and on the clock i get codes 12 and 95, 12 it says is the starting code but 95 doesn't seem to exist either?

i could really use some help, before these codes came up i got an error code for the coilpack, (forget what number) replaced it with a brand new one and it seemed better but still running badly and drinking fuel
recently replaced parts (within last 4k miles) are:
coolant temp sensor
lambda sensor
headgasket
cambelt (checked and re checked that it is timed correctly)
coilpack
ht leads
spark plugs
fuel pump (had gone faulty and completely dropped pressure)

the iscv and tps have also been replaced but these came from a scrapyard rather than new, the iscv does seem to work as it idles correctly (~800) and doesn't hunt, and the tps was checked with a multimeter for consistancy, i hope i've given enough information but i could really use some help as i'm running out of ideas
many thanks
James

Just checked on my diagnostic machine and P0200 means INJECTOR CIRCUIT MALFUNCTION.

swarp engine corsa B 1NZ-FE 1.5 VVti 110 HP >>>click>> ... http://www.opel.in.th/index.php/topic,8 ... ii4cgltc90

been driving it still in the mean time after checking all the wiring for the fueling, and checking the fuel pressure, p0200 has now disappeared but i'm not getting p0170 and again i can't find what this means? car is still drinking fuel and i still can't find any faulty parts

now getting code p1405 but can't find any pictures of what this part looks like? where can i find the dpfe sensor?

P0170 - FUEL TRIM MALFUNCTION (BANK 1)
P1405 - EXHAUST GAS RECIRCULATION FEEDBACK CIRCUIT -- egr valve problem

DPFE STANDS FOR DIFFERENTIAL (DELTA) PRESSURE FEEDBACK EGR.


so . . . the egr valve is located on the right hand side of the engine block. remove and clean then refit. use instant gasket when refitting (that blue poo). reset fault codes.

my engine is the 8v, the egr valve is located on top of the intake manifold, i've removed and cleaned this but nothing's changed, the car still judders and is drinking fuel, i've tried changing the iscv again for one that definatedly works and it's still doing it does this mean that dpfe thing is located inside the egr valve?

mapsensor?

annoyingly it's had a brand new map sensor not too long ago and it seems to be working fine

after driving it for a while long all other fault codes have dissappeared and the only one i'm getting now is P0352, the coil pack has just been replaced for a brand new one and seems to be working fine, as the light only comes on intimitantly, the car seems to be lacking on power too, i read somewhere that when it comes up with this code it sets all timing to 6 degrees, could this be what is sapping all the power and drinking my fuel?
