Engine swapped and have a question

[Cody240]

So I just swapped in a KADE into my '90 240 and at about 4000 rpm it bogs in any gear like the fuel cut out is kicking in or something so I thought it was because at the time I was running the old KAE Maf but when I got the DE maf the car wouldn't even idle and then it would sputter and die so i stuck the old one back in and it ran but it still bogs out. So idk I figured I would post up here and see if someone had the same problem. Now the swap was done with all correct parts and the harness is for that engine the only things that are not working are the speedo and tach (it because i have not gotten the DE cluster yet), and there are a sensor or two I think may be bad on the trans like the reverse sensor for the lights. What ever the case tell me what you guys think.

have you checked the spark plugs? compression?

[Cody240]

Ya they are all fine the compression was even across all cylinders and the plugs are pretty good and besides I will be getting new one soon anyway.

I would change the plugs and see what happens...the worst thing that could happen after that is it not be the problem but hey, now you have new plugs...one less thing you need. Just my $.02

Check for leaks, change plugs, time it, PULL CODES, try a NEW correct maf

Ok well I will change the plugs and do all that and try a new maf but the one I have works because I tested it on another car but any way I will see if I cant pull the codes on it at like school or autozone. Thanks
