Engine cutting out problem
I've been having trouble with a 87 RR. The EFI light has been on for a month or so and the idel has been getting rougher over that time. I replaced the stepper motor with a used item yesterday and all was well, EFI light stayed off and the RR was running great. Took it for a cruse on the hwy today and it was great untill I was going around a tight turn on an over pass. The power cut out and the EFI light cam on, I floored it and nothing happend for about 4 or 5 sec then it came back to life and drove back to town ok. Once in town it stalled a couple of times and did the power cut out trick a few times where I could floor it and nothing happens for a few seconds, twice it felt like it was running out of gas. What does a failing fuel pump do on one of these? The RR has about 200000miles and is on the original pump. Thanks for any ideas/sugestions.
