I have a 1993 Toyota MR2 Tubo with about 150,000 miles on it. For the past several years on a cold start (it doesn’t seem to matter what the outside temperature is, just that the car has sat for a long time, like overnight), if I try to drive away immediately the car will chug. It almost feels like the car is choking or is not firing. It happens mostly on acceleration above 2500 rpm and in 2nd and 3rd gears, getting worse as you go higher in the gears.
After a few minutes the problem goes away and the car will run fine. Also, if I start the car and let it idle for 5-6 minutes it seems like the car will run fine without the chugging.
Could anyone point me in the right direction on what might be the problem and how I would fix it? The car is in great shape and I hope to keep it for a long time, but I’d like to get rid of this annoyance.
Thanks in advance,
