    AC issue, loud metallic smashing.

    If you have one of them " pancake compressors " they are prone to make noise, Mine makes a hell of a racket ( kinda like a hammering / crackling sound ) when the clutch is engaged. At first I just replaced the clutch But it made no difference, so I put on a brand new one from 4 seasons and it...

    Well I got to summit racing, got some parts, the condition is still there : 1) Replaced cap and rotor with the ones that came with the new aftermarket distributor I mentioned earlier = No effect on misfire at idle . 2) Replaced wires with summit brand witch I had good luck with in the past...

    Schurkey : SUM-868858 is the Summit wires I used last time, Looking at the speck sheets they appear to be made of the same material as the ones you posted. Looks like the only thing different between the two is the color and the cut to lenght option...

    Cruise control fuse location

    When I have trouble with my cruise control and the fuse is good, I have found that either : 1) The brake switch under the dash is stuck on causing the cruise control to " turn off " ( usually hitting it with some wd-40 gets me going for a while ) 2) Some water has gotten in the control box...

    When I am reading the fine print at the bottom of the NKG ad you posted, it talks about having " 1/2 the resistance of traditional carbon core wires " Are the " wire wound " wires the same as " Low Ohm " wires ? or are the Low Ohm wires something else and the wire wound wires an even...

    1994 k1500 wild misfire

    The engine was not misfiring before installing the Autozone cap, rotor, wires and plugs , But it was throwing a SES lite and a 32 code before the Autozone parts. It was because of the code 32 and general lack of power that I initiated the tune up. The instalation of the EGR valve took care...

    Yes, I mean Ohmmeter. looks like I got 80K on the fuel filter, I have read somewhere that this may cause a random misfire so I will change that out next.

    1994 k1500 wild misfire

    New Dizzy and ICM, New Cap, New Rotor, New Wires, New plugs, New EGR valve, New IAC valve, it is not throwing any codes. The only thing I have not replaced is the Coil but It did check out OK with an volt meter test. Are these coils noted for creating a miss when they warm up ?

    1994 k1500 wild misfire

    Well, I made it out to the garage before I read Road Trips post, so I did not take any " before pictures " But this is what I found. 1) Half of the OEM wire clips that are shown in the above pictures are missing on my unit. There are some metal tabs ( #8 support in the photos ) where I...

    I am having the same issue with a random misfire as the OP after installing all new tune-up parts from Autozone ( Duralast Gold wires, cap, rotor and AC CR43TS plugs ) and came upon this thread looking for a solution. I did put a wire loom on the coil wire witch was resting on the #1 plug wire...

    PSA: 1988-1995 stumble after EGR valve replacement

    So now I am wondering, Are there also two separate EGR solenoids, and do they need to be paired together ?

    Cap & Rotor

    Did a quick search on how to test with an ohm meter, low side is reading .5 high side is reading 8.34 . I do not know if these numbers indicate a bad coil on their own or not because I do not know what they should read. I do understand that this test may not be absolute .

    Cap & Rotor

    This kinda sounds familiar, The reason why I did a tune up was because I was having trouble getting up to speed to get on the Ohio Turn Pike ( 70 MPH ) But I just figured it was because of the plugs, wires, cap and rotor had 50K miles on them. I took the coil to Autozone to have it checked...

    Cap & Rotor

    I am the third owner of this vehicle, when I pulled the coil out to give myself some room when dealing with the ICM, I noticed it was mounted on the bracket with hex cap screws instead of being rivited, there also were no GM markings on it so I suspect it was changed out by a previous owner...

    Cap & Rotor

    Looking at your first picture in post #28, and looking at my first picture in post #27 I would say that my magnet is cracked by one of the rivits also, hell I would go as far to say that your distributor looks better than mine. Would these cracks cause a misfire or low idle ? I ask...

    Cap & Rotor

    Is it safe to say that the pickup coil has the same " near forever " life span as the coil and ICM ? When I cleaned up the mess in the distributor left by the degrading cap and rotor I hosed it down with WD-40 and blew it out with compressed air, Then I removed the ICM and cleaned up the...

    Cap & Rotor

    Seeing how we are on the subject of longevity, How long can you expect a Coil and ICM to last on a '94 5.7 ? My unit has 165K and the ICM appears to be original GM unit.

    Six years and just over 50k miles ago I did a Cap, Rotor, Wires and plug replacement on my 1994 GMC Suburban, everything was bought from Summit racing: 1) The plugs are NKG R UR 5 V-Power 2) The Cap and Rotor were the "Blue Streak" set with brass terminals 3) The wires were the Summit...
