1985 325e. Changed the fuel filter after a slight hesitation started about 2K-3.5K RPMS. Decided to hot soak it and while letting the seafom sit in th engine, decided to spray the Idle control valve out with carb cleaner. Bad I dea I guess because now I have the tell-tale idle flux from 900K to 1400K in a loop. I will do some testing on it tomorrow but would that have killed it or is there any resurrecting it?
Back to the hesitation. I will test the innner and out fuel pumps tomorrow and I see that a failed transfer pump or failing main pump can cause the hasitation too. I noticed to night that the main pump seems to buzz loudly on and off. I think I still hear it running constantly, just sounds like it is going ito overload intermittently. Sounds like a pump going out... Will any E30 transfer and main pump fit this 325? I think I see some that look like it but they say its for a 318i, which I would think was a different set of pumps...
Finally the AFM. I saw a post that said the hesitation could come from some dead spots in the potenmeter(sp?) in the meter. My question there is will any 3eo AFM work as well, meaning a 325i ro a 318 e30 AFM...
