• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

    Ignition switch / Shifter problems - 2004 Impala SS

    Pulled the car out of the garage and washed it. When I went to start it, nothing. No clicks or anything. I started thinking shifter interlock or something of the sorts. Worked the shifter back and forth a couple times and got it to start. Now the ignition switch won't turn back the...

    Wideband behavior

    Finally got around to getting a wideband. Went with the latest AEM UEGO. AFR is fairly stable (within .2) at idle, also fairly stable once into power enrichment. But at highway cruise it steadily oscilates from (at most) 13.9 - 15.1. When this is happening I notice my LTFT and STFT's are...

    AC compressor runs in heat modes on HVAC

    Is it normal for the AC compressor to run whenever the HVAC controls are set on anything floor related? (Car is a 04 Impala FWIW) I'm not crazy about having my AC compressor running all winter long so I thought about bumping up the min IAT to enable AC and see what happens.

    Rebuilt trans: New noise

    So got the car back from the shop from having the trans rebuilt (including a reman converter) I've got a new noise. I could best describe it as a faint hollow knock. Faint enough that most average car owners wouldn't notice it. But I'm OCD and hear everything. In fact at first I was paranoid...

    Having trans rebuilt - questions for shop?

    I'm having my high mile trans rebuilt here locally by a shop I've used in the past and trust. It's got 190k on it and has the slip then bang issue when stopping at redlights occasionaly. I've already done the Transgo kit. Is there anything I should request them to do while they're in there...

    3.5" or 3.6" pulley

    I'm finally ready to give in to temptation and drop pulley size. The zzp charts are a little confusing. The car is a 2004 Impala SS, but they say 3.5 should be stock. Mine is no doubt 3.8. I'm running Autolite 104 plugs, 180 tstat, 2.5" catless zzp downpipe, and a very basic tune. Have at...

    Wheel sensor going bad again in new hub?

    When I got this car I chased all kinds of ABS issues and finally got it all fixed. (New LF hub, and new RF harness) One was a bad wheel speed sensor in the left front. About 1000 miles later I'm getting a C1225 LF wheel speed excessive variation. Sounds like my new hub is a piece of crap...

    Back window replacement - non-onstar vs onstar glass

    Need to replace my back glass because we screwed up the defroster in the process of removing tint. My car had on-star, but of course it doesn't work so I removed all the crap for it. Can I get a non-onstar window to replace it? Not sure if the defrost connectors would be the same, etc.

    Trans shift time, pressures, and force motor current

    So decided to tinker around with hptuners on my car. I want to firm up and speed up the shifts a bit, but nothing crazy. Mostly to prolong the life of the tranny during daily driving. I've been comparing a lot of files to the stock tune, but they seem to be all over the place. I don't...

    Exhaust gasket part numbers

    Does anyone know the part number for the gasket that goes between the front exhaust manifold and the crossover pipe? Also, the rear manifold to the ZZP 2.5" downpipe (I assume the stock one will work here) Then lastly the downpipe to the rest of the stock exhaust? I pulled up the walker...

    Stock rocker arm bolt source?

    I was looking for torque specs and I see our rocker arm bolts are TTY. But I can't seem to locate any beside GM. Are they re-usable? I'm finding mixed things on this. Doesn't Rockauto carry them, or am I searching for the wrong thing? [EDIT] I'm dumb. I found the re-usable comp bolts...

    LIM side coolant port modification / coolant block off

    Ive got my new (j.y.) motor on the stand. Gonna regasket the LIM before I put it in the car. I don't know if I'm going to block off the coolant ports to the blower or not. It seems like a 50/50 mix of folks saying to do it or not. The car is just a driver that will see all seasons...

    2000 trans in a 2004 car

    My car is an 04 Impala SS, got a line on a motor and trans from a 00 Regal GS. I need the motor, but wouldn't mind swapping over the transmission with half the miles as mine too if it'll work. Will this work, or what will I run into? At most I've read about some electronics changes in 04'...

    Piston damage

    So finally got the heads off this motor, and this isn't what I expected to find. Is this the product of detonation? Kinda looks like something bounced around in the cylinder, but the walls look fine. 189k mi motor, pulling it apart for a failed headgasket (burnt between #1 and #3). I'm...

    Engine interchange - Model year differences

    So I'm motor shopping for my 04'.. (Bad head, I can get a complete engine for around the same price as machine shop alone) The yard I'm talking to will sell me the entire motor, accessories included. What's the best year range to look for? I'd prefer to be able to re-use everything off the...
