Hi, i love this form because no mechanic can give advice like the boys on here..... so heres my problem..... I replaced the abs pump and motor ran fine for a couple months... took it in for an oil change got the car back ran fine for a while then started running like it was on 4 cylinders. Check engine light came on. As the car sat and idled for a bit the temperature slowly started to climb. the check engine light went off and idled fine. I drove it for awhile ran fine. Next morning i fired up the car idled fine for 2-4 minutes then started idling rough again. I noticed it takes along time for the car too heat up but maintains a normal temp when idling in traffic or my driveway. The Low speed fan did work but doesnt anymore, just the high fan when temp gets to m of NORM. I have repaced the ECT AND The tempereature senidng unit sensors. i pulled codes and i got 67 and 45 with key on engine off. with engine on i got 72 73 25. I think i have pinpointed everything to the DIS module, but im not 100% sure. 1 last thing is when the car heats up to norm temp there is a little hissing coming from the rad cap. If i had a faulty cap would it cause the car to run like it is on 4 cylinders??? any input is appreciated
