I noticed sometimes when I turned key over,the car would fire right up but the rpms would jump around like it was going to stall, but then it would smooth out in a second or two. this wouldn't happen every time though. the car otherwise runs flawlessly, no stalling,no loss of power, nothing. I'm getting good mpgs and everything.
today I went to eat lunch at the office. I left the office about 30 minutes later and when I went to start the car, it cranked for a while before it would start, maybe 15 seconds. then all of a sudden it fired up and ran flawlessly after that.
I did the upper and lower intake gaskets a few weeks ago, but his startup thing has happened before that repair (mentioned in first paragraph). it was just today that it took that long to start.
I cleaned it maf sensor when I did the intake gaskets but that's it. I also had a map code before I did the gaskets and I replaced map sensor and code went away. I smell no gas and have no gas leaks. I haven't done a tune up to the car because it RUNS fine imo.
I do notice sometimes when It starts, the blower motor takes a bit to blow full power and the car feels like it has to "catch" before reaching regular rpm.
any ideas?
