Robert, Here is the information I have for Volvo to DeLorean Idle Speed Motors (Regulator) compatibility Volvo 1979-1981 260 & 264 GLE Volvo 1982-1987 760 GLE The 740 is equipped with a non-PRV four cylinder engine, the 79-81 260 is a perfect match sharing the same Bosch CIS fuel injection with the DeLorean. I have first hand knowledge on this subject because I previously owned an 80 260 and now own a 89 760 in addition to my 260k mi. DeLorean.

The 760 uses a different type of motor. The 740 will not be easy to get to, as the ISM is located under the intake manifold. Don't even bother looking at the 260 for a match. It uses an entirely different type of regulator to control the idle with isn't compatable either. -Robert vin 6585 --- In dmcnews@xxxx, Delorean17@xxxx wrote: > Hi, > Ever since I have purchase my car it has had a small idle problem. > Sometimes it acts like the microswitch isn't engaging and will idle around > 1300 Rpm's or so [Non-text portions of this message have been removed]
