Saab 9-5 2.3t B235 engine misfire

[pisani01]

I see alot about replacing with NGK plugs is there any problem putting in the Bosch plugs ??

You should never ever ever use anything else than NGK spark plugs in a Trionic 7 system. Nothing else need to be said about that.

ok but what is the prefered NGK number that doesn't cost an arm an a leg?

[frav]

Most T7 engines use the cheap NGK BCPR6ES-11 or NGK BCPR7ES-11. In the B2x5R engines (Aero) the more expensive Platina Long-Life NGK PFR6H-10 are used. But you can use BCPR plug in the R-Engine also. You just have to replace them more often than with the PFR.

You can find the right spark plug spec for each engine here: http://saabworld.net/f144/spark-plug...ication-27621/

thanks i am having those buggy codeswith the cel and the plugs in there now are the denso i think I did pull and the seemed burnt not sooty so I will get the NGKs

[pisani01]

thanks for the reply I have p1312 p1334 and p0340 codes and I did put on another DIC

[pisani01]

I did put the NGK plugs in cleared codes. I took a short trip with three shut offs and restarts on the third cel stayed on ? I will read codes later to see if they are the same i've been getting.

I took the DIC apart and cleaned the coil contacts they had corrosion on them wonder if some of this is a problem any thoughts guys?

What TK-version of the DI cassette do you have? TK3.7 is the latest & the only one you should use with a Trionic 7 engine.
