#101 of 165 96 deville idle ;problems HELP! by devillian Mar 19, 2006 (2:05 pm)
at about 41 or 42 mph when the car shifts into last gear and you are giving it some gas it starts to cut out and wont go. it stops at about 50 unless u are flooring it. Also just recently the car ONLY when in drive starts going from 625 or 650 rpms to like 700 then down to 575 and it makes a jolt, kind of a shake. other than that the car runs great. any ideas?? would be greatly appreciated.

Replying to: devillian (Mar 19, 2006 2:05 pm) Try having a mechanic test your M.A.P. sensor. It's the module that controls the air/fuel ratio for your engine. It could be the reason for the inconsistant RPM's and lack of acceleration. I had a simialr problem with my 86' Mustang and had it fixed for around $300. Let me know how it goes...

Replying to: pmetz (Jun 27, 2005 7:19 pm) I have had this problem with my 1997 Deville. But, I have never gone to a dealer to have them fixed after warranty. It only takes about thirty minutes to change and they cost about 23 bucks at autozone. My suggestion is to check the wiring harness. The reason mine kept going out was the exhaust manifold was melting the wiring. After putting heatrestant tape on them, I've had absolutely no problem.
