90 gtu help

ok so with my sr240 totaled i got a nice 90 gtu, ok long story short it has a hard time cranking up takes about 4 or 5 good turns with gas depressed to crank over, when it does crank it runs smooth with minimal smoke, it idles rather high at 1300 rpm on top of that, im going to check into the tps and see if i can lower it a tad. ive heard that when theres cranking issues like mine that they engine may be on the way out ?

im somewhat familiar with early 13b's having owned a gsl-se but this s5 seems foriegn compared.

Do a compression check and that will tell you about the health of the engine. Hard starts can be the result of a number of things as you probably know. If the engine compression is within spec, start checking out the obvious things starting with the spark plugs.

BTW, unless the engine is flooded, leave your foot off the gas pedal when cranking the car. I believe that cuts the fuel on an S5.
