Hey guys im having a bit of a problem in my sol.... I bought it with the b16a swap already, and it came with and was running on a p28. Well with the p28 in, it started to kind of lag out in vtec. So I checked the oil levels, the timing, and then thinking it coulda been a spun bearing like my ls vtec did. I took off the valve cover, vtec selonoid and the oil pan... Everything looked pretty clean with no debree or metal shavings.

So I did some more searching online, some people were having the same issues and said that they swapped ecu's to a p30. So I got a usdm obd1 p30... Solved the sputter/lag during vtec problem, but now with the usdm p30 it will kinda lag before vtec. Feels like it isnt getting enough fuel or something..

SO then I replaced the plugs, wires, fuel filter, and the oil change.. Still lagged before vtec.

I was then told that using a JDM p30 it should be ok cause the motor is a jdm swap?

Got the jdm p30 and it still has the lag before vtec problem...

Do you guys have ANY idea's of what this could be??
