I purchased the correct MAP sensor ( MAP ) No longer throwing a CEL engine still idles rough. I have tested the fuel pressure at fuel rail 45 PSI at idle, drops to around 5 psi with key off. Removed and cleaned IAC Reset the IAC adaptions (jumped pins and cycled ignition and removed fuse)...

Only the OEM map sensor allows the truck to idle. And none of the other sensors have the same ridges. Possible that all these other sensors are 1 Bar?

Code 34 now displaying when at idle. CEL illuminated. Tested voltage at MAP sensor 4.5v. Can throttle and put engine under load but when it comes back to idle engine runs very rough and stumbles. Noticed when at idle and I jiggle test or touch MAP sensor the vehicle will die. Here's a video...

Thank you, I was able to get the map sensor working and the vehicle idles. But I have a new issue, I was testing my throttle position sensor and sweeping and monitoring with my multimeter and it looks like when sweeping the sensor it cuts out. So when I idle the truck it has no issues but when...

Okay with new MAP sensor installed ACdelco brand 213 1545 with the connector corrected cluster showing full boost position two ignition. With the OEM sensor in it shows as you described. Not sure if this AC Delco brand is correct.

I will give this a shot thank you!

I purchased this MAP sensor. Seems the connector on my truck does not fit the new MAP. Do I have to purchase a new connector and splice it?? Thanks.

I recently purchased a new MAP sensor for the truck but I am seeing some Ebay sales with 2BAR MAP sensors turbo boost with wires, mine did not include wires? I see the GM 16009886 is discontinued and I am unable to find an OEM sensor. I have called around and I am hearing MAP sensor needs to be...

Thank you for the info. Im leaning more toward the cluster side of this mystery... I found temp gauge needle will move now when I hit a bump... It will begin working after being jostled... May be a connector backing out or a ground issue. Ill let you know about my findings when I unsolved it...

Thank you!

But this scan master looks bad ass.... I may have to look further into this option.

Thanks for the response. All good info. It will show like it's not reading for a good 30 minutes at idle then it will show likes it's slowly climbing not even to the first peg on the gauge then back to nothing. I have drained and vacuum filled the cooling system. I'm starting to think it's more...

Hello! I just purchased a Syclone that has been sitting for 17 years. It runs and drives great but the coolant temp gauge is having issues. I'll run the truck and take it to work and back but the gauge will raise a small amount then drop down and not read. I have replaced the coolant temp...
