Re: Stalling - Where to start?

Auto parts stores can test the ICM. Make sure they get it good and hot, to replicate the under hood environment.

Pulling the codes is important because the Opti and ICM codes that can shut down...

Re: Stalling - Where to start?

At any point have you scanned it for codes?

What brand is the Opti? Lot of poor quality stuff on the market. Have you had the ICM tested? Definitely follow up with the fuel pressure.

Is the...

Re: water pump failure doing surgery at 141k miles

At least 22 years since I pulled the Y-pipe on my 94 to install headers, but I do not recall gaskets being present. The 93 factory service manual assembly diagram does not show any gaskets for the...

Re: So frustrated losing interest

Have you actually opened the cap to see if the coolant is low?

If coolant is low, are you following Shoebox's procedure?

if coolant isn't actually low, the sensor is a common problem. You...

Re: 94 LT1 Corvette owner from Sweden having Opti problem

No. The mass air flow sensor measures the actual mass (not volume) air flow into the engine. The clogged air filter will cause loss of pressure, which reduces the density (and therefor the mass) of...

Re: 94 LT1 Corvette owner from Sweden having Opti problem

Low (below 128) LTFT's would not be due to a vacuum leak. A vacuum leak would cause the PCM to move the the LTFT's above 128, in order to supply the extra fuel for the vacuum leak air, that is...

Re: water pump failure doing surgery at 141k miles

Shoebox's cam remove and install guides have valuable info on removal/replacement of the water pump, Opti, crank hub, front cover, and timing set. Just ignore things required for cam removal (like...

Re: Fake Hypercar (VIDEO)

Re: Hesitating and sputtering lower RPM (datalog)

Glad you got it worked out. Not sure if that problem would have shown up in the data log. Were the intake valve burned/leaking? If it was just one cylinder, could have caused MAP to read a bit...

Re: 94 LT1 Corvette owner from Sweden having Opti problem

I downloaded the new file, and it look like the old one, after you sprayed the cooling material. Just out of curiosity, what is that material?

Just like the first file, it shows a very stable,...

Re: Dtc 41 & 42

If it started with DTC 42, it's had to be a stored code, not an active one, and the problem is intermittent. When DTC 42 is active, it shuts down the injectors. And DTC 42 can only set during...

Re: Car seems to go lean at WOT

I thought about the Opti. But that would take a series of misfires on both banks, and I can't think of a failure, other than in intermittent loss of the low res signal. Then the question becomes,...

Welcome to CamaroZ28.com (http://CamaroZ28.com) ! ! !

Hope we can help you out.

I did look at the data log Gary attached. I see the problem, and the interesting thing is that the erratic idle...

Re: 94 LT1 Corvette owner from Sweden having Opti problem

I'll take a look to see how well it matches up to what I have seen in the past with false RPM spikes from the MSD Opti’s causing erratic idle. MSD reportedly traced the problem to the cap, and...

Re: Car seems to go lean at WOT

At 10 frames/sec, the above about 1 second. Appears it's an intermittent lean.... not continuous. Pulse widths don't fall off, only the O2’s. It seems to be in PE (recognizing the limits of the...

Did you check the voltage and ohms to ground on the ICM connector per Shoebox’s guide?

Re: Car seems to go lean at WOT

Somewhere in there is a table of RPM vs. throttle position that sets the parameters for entering PE mode. It isn’t entered only at WOT (100% TP%). Check your TPS to make sure it's producing...

Re: Dtc 41 & 42

Check the ICM connector, as shown in Shoebox’s guide. Sounds like a short in the connector or the wiring. Jiggle the cable and wiring during the test, to look for an intermittent condition.
