HELP! Severe acceleration lag

JARblue

I thought timing wasn't pulled until 250ish temps? Plus thought it was weird that he only notices it at lower RPMs ... if heat related it should still be pulling timing at higher RPMs.

Not that an oil cooler is a bad idea by any means. It just sounded to me like normal stock throttle lag, although heat soak on this car is a bitch and probably guilty as well.

If his oil temp is is in the 225 range, IAT is probably high. Especially when sitting at a stop light - IAT is going to rise if stopped for more than a few seconds. My guess is that the problem would not be as bad if only stopped for a second or two (eg, stop sign with no cross traffic).

IIRC, timing is pulled across the range of RPM, but risk of pinging if greater at lower RPM so timing advance is reduced more.

Yeah. Probably a combination of both.
