Hard Restart and misfire.

[88t]

Hey guys,

Little back ground with my car, 88 turbo 5 speed with 3 inch exhaust, intake, arp bolts with toyota gasket, new clutch and what not.

Since i bought this thing 2 years ago, its been hard to start when it was cold. It would take aleast 5 seconds to start, sometimes twice. Never thought a thing about it, just thought it was how it is.

after a drive, if i stop somewhere, like the gas station, i go to restart and it idles really low and cuts out. I have to give it gas and when i do it mis fires like crazy then smooths out.


there is a misfire that i cant get rid of, i have a hole in my downpipe (which just happened so rule this one out?) and i still get 21mpg.


i have the autolite plugs at gapped at 28. boost set at 8 pounds. other then that everything else is stock.

You might want to look at the cps connector. They get baked. Pull on the wires a little at the connector to see it they are good.

+1 toyotas hate autolites. ngk, denso or nothing.

as for the hard start issue (deal with this issue first) does it help to open the throttle slightly while cold starting the car. also try jumping (fp to b+) in the diag block (with the key on), before your next cold start. and see if that helps.

im going to try this. i have a hard start too. but no misfires. just takes bout 10-15 secs to start every morning. then 3-8 when its warm.

mine also does the warm start stumble...no codes either. slight throttle and 5-10 sec. it clears right up.

Makes SUre Theres No OIL Anywhere near oR on ur SPark PLugs ..whens the last time u changed ur Spark PLug Wires

 

[88t]

there is no oil in the spark plug valley, and spark plug wires are in spec with ohms in tsrm. Will have to try new toyota plugs on payday.
