Wish I could lie, but I can't. There has been an idiot working on my car. After last post I went to sit down for awhile and picked up my Chiltons. Looked at the firing order and CCCI pack positions. Can't lie - had 3 cylinders wrong for over 2 days. Changed them and the intermittant miss that...

Checked coil part of CCCI and found 0 - 14K ohms depending on which pair of towers is checked. Put on new CCCI upper module. No differance except there are now 6 7K ohms on all 3 pair of coils. Last night with the old coil, 3 cylinders were firing good and 2 intermittant with 1 dead using a...

I unplugged my CCCI and ran a compression check. 150 psi. Put in new AC44TCS plugs, plugged the CCCI back up. It started but backfired a few times and runs flat like the plug wires were crossed. They aren't. Could the CCCI be out of time with the crank and cam??

I notice some new posts on emissions failures. This was my first year to have to pass. Had problems. gofstbuick sent me in the right direction. The basics. Emissions technician worked with me at all of the failures (3) and I tried a lot of stuff just like most of the posters. When I changed the...

Posted on general tech board. Maybe somebody can help me on this board. Can catalytic converters stop up like a collapsed exhaust pipe? Ran compression check looking for an intermittant miss. 150 on all 6. Put in new plugs. When I did the comp. test, I unplugged the Cal Pak. Plugged it back in...

Car was running fine with a slight popping noise like a bad exhaust valve. Ran a compression test and got 150 on all 6. When I ran the test I disconnected the Cal Pak. Would cranking the engine over with the Pak disconnected get it out of time?Changed plugs twice. Tonight I was working with the...

Have had an intermittent miss and started by doing a compression check. 150 all cylinders - good. Rules out exhaust valves. After running the compression, I put in a new set of ac plugs but r42's. Engine stock except for K&N, chip, and flowmasters. When I did the compression check, I removed the...

Thanks to gofstbuick for sending me back to basics. Passed emissions test today with following #'s: Highspeed: HC=13 CO=0.00 CO2=14.9 O2=0.4 NOx=97 Dilution=14.9. Low Speed #'s are: HC=14, CO=0.00, CO2=14.9, O2=0.4, NOx=59, Dilution=14.9 Method gofstbuick suggested for checking EGR Valve & TVS...

Failed hydrocarbon part of emissions test. HighSpeed: HC=152 CO=.62 CO2=14.1 O2=1 NOx=268 Dilution=14.7 #'s for low speed are:185, .67, 14, 1, 418, 14.7 Received a Recall information form saying the PROM had to be replaced. Dated 06-01-1992. Am not getting EGR operation because there is no...

What I have found on A/C vibrations: As turbo dave pointed out, all bolts have to be tight. Every single bolt to every accessory bolted to the face of the block has to be tight. To be sure an accessory is the cause of vibration, remove belts on earlier models and serpentine belt on later. If...

Have a vibration from accessories. Remove belt & vibration goes away. New A/C compressor. Was vibrating before new compressor. Has anyone had a problem like this. Vibrates through the console. Turn A/C off & it stops. Drew
