Too many cranks before start and fuel consumption

[u mad?]

why's that lukey?

if its changed every 10-15,000ksm like you should - there shouldnt be an issue ?!

how can bosch be bad...its German. lols

I believe my car's spark plugs were changed 4000km ago by the dealer when they did major service.

I paid $2.50 each last time I bought NGK copper plugs. Definitely get them for a stock B18B.

OBD1 ECU has long term fuel adjustments. Maybe try resetting the ECU? (seach it)

My sister's GSi chewed fuel when the thermostat died. Pretty sure that it slowly got better after I replaced it.

Yeah i've resetted the ECU twice since thermo change. Once i let it learn to drive hard and then i did it again driving calmly. Nothing's changed.

string, what was your sister getting before and after thermo change? (fuel economy)

[string]

She was getting about 325km out of a tank now she gets about 400km (from 45L I believe?). Hers is manual, though. She definitely doesn't drive it economically

O2 sensor has massive influence on fueling when you're not foot to the floor so if it's borked it could be the culprit. No clue how to check it though, sorry.

The cold cranking worries me. Does the car go through coolant?

[charliebrown]

325 with broken thermo still hella good. I'd take that over my working thermo lol

[string]

Automatic definitely hurts it a bit. Heavy stop-start traffic can easily double your fuel consumption.

I don't mean to be a downer but there's just something about the GSi that makes it get bad fuel economy! Lol! I suspect that the lower (4.26) final drive doesn't help. I know it's a little bit heavier (the GSi), but I never got worse than 10L/100km when I had a stock B18A in my DA. It's difficult to keep all the variables equal though; everyone drives differently. I (and my sister) live in Newcastle. The traffic isn't so bad here, and I'm adept at avoiding it.

[charliebrown]

Yep, that was my reasoning for wanting a manual.

My drive to uni is about 10km, takes 30-40 minutes. Would that affect my fuel usage heaps? Still shouldn't be that high

[string]

Honestly, it's impossible to say for sure over the net. 30-40 minutes for 10km sounds pretty horrible and absolutely conducive to worse fuel economy, but exactly how much worse is hard to say.

If I were you I'd take up dougie_504's offer. An experienced eye is priceless.

It was chewing coolant for a few days after thermo change. It's alright now i think
