Intake tube on 4.9 with Allante Intake?
(Archive: TD&Q - by FieroMaster88, started: 12-31-2005, last post: 2006-08-11 13:10:54 CEST)
One of my projects I'm planning this winter is to create a cold air intake for my 4.9. My only issue is I have the Allante intake which has an oval throttle body. I need to know what others have done to adapt some 3" intake tube to the Allante (or SBC) oval throttle body? I want to end up with...

WinALDL with caddy 4.9
(Archive: TD&Q - by Cplensdorf, started: 08-01-2004, last post: 2005-01-19 11:12:01 CET)
Can I use WinALDL with the caddy or do I need a scanner? What scanners work?

4.9 owners neat cooling mod
(Archive: TD&Q - by Capt Fiero, started: 11-30-2006, last post: 2009-02-19 10:46:24 CET)
My caddy ECM and I presume all 4.9 ECMs are built to control 2 separate fans. I chose to use the Caddy ECM output for my fan control rather than the old style Fiero fan switch. This proved to be a good choice. The issue was that I could not decide which fan output I wanted. The first fan was...

ATTN: Rockcrawl. 4.9 Computer questions.
(Archive: TD&Q - by Jncomutt, started: 05-31-2002, last post: 2002-11-04 12:03:01 CET)
I will have my 4.9 actually in the car in about a week. I just finished sanding the cradle all down, painting it, and installing the poly bushings. I'm sure there are still MANY more 'in car' hours left to go before the computer/wiring get done, but I like to get jump on this early.I have the...

4.9 Pressure Plate Torque Spec?
(Archive: TD&Q - by arte444, started: 10-28-2007, last post: 2009-02-19 10:44:35 CET)
The book says 15 ft. lbs and since I have a spec stage 4 clutch and a 4.9 is this going to be the correct torque spec? What have you guys used? I've got the red threadlocker also =)

Swapped Trans now no shift (4.9 & 4t60E)
(Archive: TD&Q - by Racer_JT, started: 08-17-2004, last post: 2005-01-19 11:11:18 CET)
Well I got the trans swapped out was 93 deville w/2.73 now 94 Lumina w/3.42. It seems to me it is in limp home mode. It only has third gear when in drive. I can get it to start in second if I manually shift it down. I have rockcrawls chip that is reprogrammed for the new tranny. Any...

4.9 on the road
(Archive: TD&Q - by jfoster142, started: 03-29-2011, last post: 2013-03-14 10:12:20 CET)
Well my 85 notchie is converted to a 4.9 and 4T60E. I've put 1800 miles on it since the conversion with only a couple of minor hiccups. I had an oil cooler line spring a leak (wrong type of hose used) and I had an intermittant electrical hitch that took a while to find. Turned out to be the harness...

4.9 4T60E VCC operation?
(Archive: TD&Q - by NJD85GT, started: 09-10-2011, last post: 2013-03-14 10:11:13 CET)
Put one problem on hold, on to the next one! I have had an issue with the VCC clutch on my 4T60E ever since I bought this car (even when the PCM was unprogrammed). My VCC clutch will only engage above 55-60 MPH, both in 3rd and 4th gears. It doesn't follow the tables in the computer, it should...

(Archive: TD&Q - by RHKFiero, started: 08-26-2008, last post: 2009-09-07 11:03:50 CEST)
I've got a 4.9 Cadillac build that's just about complete, just need a few odds n ends. One of those is the air intake hose. I've got the Stock 4.9 Cadillac (1993 deville, IIRC) intake, and I'm looking to mate that to the stock 87 Fiero 4 cylinder intake. I'm sure a lot of you have done this...
