I have a 95 Del Sol with a B16 swap, about a month ago I noticed my car lagging at half throttle and then all of a sudden it just let's go. While it lags my car also jerks like it's being restricted. I've changed my o2 sensor, injectors, temp sensor, ignition coil, and spark plug wires. People tell me it could be my map sensor, or something to do with my intake manifold. Can anyone please help me????

 

Bump for an answer.

 

what do you mean it suddenly lets go? it stops lagging?

 

yea it stops lagging

 

i dunno..maybe your iacv can be stuck at that certain spot and once it gets past it its fine? oh joy..another thing i need to research and find the answer to!..the learning is never-ending!

 

I'll try that out, thank you

 

It was my ECU
