SOURCE: need to replace turn signal switch 93 cadillac deville

First do you have a sterring wheel puller. Can't remove the steering wheel without one. Quite an involved job including snaking the electrical connector end through the steering column. I wouldn't recommend it to the novice

SOURCE: 2001 Cadillac Deville won't stay on after turning

EIther the IAC or throttle postion sensor is dirty or faulty. Or leaky vacuum hose somewhere. As long as it is not missing and running weird, then you may have bad coil packs.
You can go to autozone.com and register for free online repair manual for your vehicles if you need it.

I baught a 1984 caddilac coupe deville that was sitting for 7 years and when i try to start it sometimes it turns on for like 5 seconds and turns off. If i try steping on the gas pedal it turns off...


check your timing. Cadillac use to use a plastic timing gear that would easily strip. Replace it with an aftermarket gear made of metal and you won't have problems for a long time. Why they used a plastic timing gear is the stupidest thing I have ever heard of and when I found that out I vowed to never buy a cadillac again.

Can a 3800 series 2 v6 replace a ht4100 v8 in a 1986 coupe deville?


Sub frame , wires, computer, BCM are all different. A 4.5 or 4.9 engine will fit if you use your intake and gaskets for a 4100.

I need to know where the plug wires go.from spark plug to distibuter cap on a 1986 4.1 coupe deville(cad.)


FIRING ORDERS NOTE: To avoid confusion, remove and tag the spark plug wires one at a time, for replacement. If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your book to reflect how your engine is wired. Fig. 1: GM (Cadillac) 250 (4.1L) V8 GM (Cadillac) 273 (4.5L) V8 Engine firing order: 1-8-4-3-6-5-7-2 Distributor rotation: counterclockwise 85872009.gif Fig. 2: GM (Oldsmobile) 307 (5.0L) V8 GM (Oldsmobile) 350 (5.7L) V8 w/EFI Engine firing order: 1-8-4-3-6-5-7-2 Distributor rotation: counterclockwise 85872009.gif Fig. 3: GM (Buick) 252 (4.1L) V6 Engine firing order: 1-6-5-4-3-2 Distributor rotation: clockwise 85872010.gif Fig. 4: GM (Cadillac) 368, 425, 472, 500 V8 Engine firing order: 1-5-6-3-4-2-7-8 Distributor rotation: clockwise 85872011.gif Fig. 5: GM (Cadillac) 429 V8 Engine firing order: 1-8-7-2-6-5-4-3 Distributor rotation: clockwise 85872012.gif prev.gif next.gif
