1jz hesitation.

[driftouteast]

Having a few troubles with my car. Yesterday me and a mate changed the spark plugs on my chaser (1jzge). Drove home and it was fine. But this morning as i was leaving for work this morning, i put my foot down and it started hesitating quite badly. I then came up to an intersection and came to a stop and it started to die on me so i gave i a bit of a rev. As i drove off and it changed into second, there was quite a loud clunk from the engine bay.

Had to drive to work like this as i had no other way to get there. I had a look at the leads to see if they were all on properly and took it for a drive at lunchtime, and it was fine.
But when i left work the same thing happened again. When i got home i pulled it to bits again and tripple checked that the plugs were in tight and the leads were on properly. Put it back together, took it for a drive. All was well until i turned around to come home. The hesitation isn't as bad, but it is still very noticeable. Now im unsure as to what to look at.
Any ideas/suggestions would be fantastic.

Edit: forgot to mention this only happens on a flat or going up a hill. Going down a hill it drives fine.

Plugs are NGK BKR6EKU. We didn't have a gap tool, went to repco and supercheap today and they said they have never heard of such a tool

Strange it says they should be BKR5E not 6. All my research said tey should be 6E

[FLAWLES]

they should be ＢＫＲ５ＥＫＰＢ１１ dude

you have to cold of a plug, and i would also say they would not be gapped correctly that or your coil packs may have a small crack in them causing a possible miss fire

[Jonno2002]

bkr5e will do fine, dont need platinums or 2 ground electrodes, and just go with the standard .8 gapped plugs not the 1.1s

[driftouteast]

Ahhh ok. Ill get some tomorrow and give it a go. Will let you know what happens.

[FLAWLES]

fully dont need to get platnums
