4JX1 Isuzu Blocked MAP sensor 

Thanks, the hole was indeed blocked and i had very sluggish performance

Hi there, I'd like to see a video that shows how to turn on the turbo, on opel monterey rs 3.1 td, 1993. Its not working since the engine was switched. Thanks!

Loving your channel Sir.........I see there is no filter between the map sensor and manifold, my isuzu wizard 4jg2 has one. Do you need an inline filter ?

Can you tell me whether the set up is the same for the 4JG2. Have a '96 Bighorn which has done me well but currently surging/dropping gears whilst in motion. Suspect it's a simple enough issue once identified so checking into the IAC also.

How did you know when the EGR valve worn out?can you check it manually?

Hello, I have a isuzu trooper 1994 and the check tramission light keeps on flashing . So I scanned the obd-1 and get back to code 23 but two definitions one is mat circuit fault and the other is map sensor fault or mat sensor ? Which one is correct and relates to the transmission? I scanned the transmission

did u clean also the exhaust gas recirculation valve

what if something hard is blocking it?

If mixed diesel and oil wath wit me make
