I recently got this bike for 1k but it needs a new engine or replated or something im not sure what I got into i bought it knowing what was wrong but the engine has some pretty bad scoring so how do I go about fixing it would it be good to get it resleeved?
I have a 1992 325is with the m50b25 and I cant figure out why my idle "surges" once it warms up and its cold start idle is only 800 then it drops to around 600 rpm and then it starts jumping from 600 rpm to sometimes 1100. Ive replaced my ect sensor for the dme, my o2 sensor, maf sensor and theres zero air leaks and my icv is working, what else could it be??
